iPad mini casing
Could this be the new iPad mini casing?

The iPad mini has been on sale since November 2012, so when will we get the iPad mini 2?
It seems like Apple was surprised by the iPad mini demand - it sound three million of the new iPad 4 and iPad mini in three days.
The story goes that the iPad mini 2 will have an even sharper display of 2,048 x 1,536 pixels packed into the same 7.9-inch space.
RBC Capital Markets analyst Doug Freedman - who was in China visiting chip companies in mid-December 2012 said: "iPad Mini Gen-2: Apple's gen-2 iPad mini is getting pulled-in, and is likely to have several new suppliers, with TXN gaining content."
When retailers start to price cut that can sometimes mean they're making way for a newer model, and as Cult of Mac notes, in the US that's just what Wal-Mart, Best Buy and MacMall are did on Wednesday 3 April, reducing prices of the iPad 3 and iPad mini prices by about 30%.
And could the iPad mini 2 also have the A5X processor under the hood? It seems likely, but as GottaBe Mobile reports, it's unlikely that Samsung will be the manufacturer of whatever part appears in the device.

Images of what could potentially be the casing for the new iPad mini 2 leaked online in February. The photos come courtesy of the Chinese Weiphone forum, showing a silver rear casing for an iPad mini.
Most immediately noticeable on the casing is that the Apple logo and text is a sky blue color, rather than the typical black.

After you get over the color distraction, the more important point is a more subtle difference from the current mini, in that the casing appears to indicate a thicker device that the existing model.
The iPad gained a little extra girth when Apple upgraded it to a Retina display, so a thicker casing in these alleged iPad mini 2 shots seem to point to some Retina presence in this model.
iPad mini 2 release date

With production of the sharper screens projected to start by the later half of 2013, the iPad mini 2 release date could be mid to late 2013? And could it be that April is the release date for a revised version as well as the debut of the iPad 5? It doesn't seem that likely.
Ming-Chi Kuo, a financial analyst with KGI Securities, has published what is believed to be a leaked roadmap of Apple products for 2013. That points at an iPad mini 2 being released late in the year.
BGR cites a pair of reports that agree with the late 2013 release date, in time for the Christmas rush.
iPad Mini 2 display

The grown up iPad 4 has a Retina display, and the next mini should either have that Retina tech or something similar.
The biggest criticism of the current iPad mini so far is its relatively low 1,024 x 768 resolution. Critics wonder why a Retina display wasn't incorporated into the first iPad mini to begin with, but it seems it was largely to do with the speed of the product's announcement.
Some said Apple went with a lower resolution so it had some low hanging fruit to grab for the next upgrade. Production problems surrounding the iPad mini might also be the culprit.
The forthcoming iPad mini 2's retina display is said to have a resolution of 2,048 x 1,536 pixels, doubling the current iPad mini's 1,024 x 798 screen and packing more pixels than the iPad 4's 264 ppi.
Anand Lal Shimpi and Vivek Gowri of Anandtech suggest that there are three things Apple has to do to bring a retina display to the iPad mini.
Reports in February 2013 suggested the iPad mini 2 retina display was already being manufactured. It's suggested that it will have a pixel density of 324ppi. As we saw with the iPad 4, could a better iPad mini 2 display also mean a bulkier product? Not it, as rumours suggest, the screen is a tough Sharp IGZO display.
GottaBe Mobile believes that Apple will certainly "actively [move] away from Samsung for the next generation of mobile products." Apparently Apple sent out a request to parts manufacturers for estimates for the iPad 5 and iPad mini 2, Samsung was not a recipient of the request.
iPad mini 2 price

When the iPad mini was first released, reports said the steep price point of $329/£269/AU$369 was due to manufacturing difficulties. Indeed, well into early 2013, iPad minis were not shipping quickly.
The new GF DITO touchscreen technology that helps make the mini so small is reportedly one of many production hurdles.
AU Optronics (AUO), the company that produces the current iPad mini LCD panels, was also having yield issues with the mini screens at first, so a Retina-like display could have caused additional production headaches.
However, AUO claims it smoothed out production problems surrounding the current panels, already resolving the light leak issues that held up fabrication.
Would a retina display iPad mini 2 also push the price upwards? There may also be retina and non-retina variants to keep the basic price low.
