Way back in February at MWC Chippy spoke with a Dell representative who confirmed that the Dell Streak (aka Mini 5) was one of a family of upcoming devices. Since then we saw leaked renders in April of a 7” and 10” Streak device courtesy of Engadget.

Jump to almost 9 months later and we find a Streak device passing through WiFi certification (this actually happened back in November, but didn’t get uncovered until recently.) The device could be one of several different sizes of Streak devices, but a commercial concept leak from Engadget lets us assume that the device is in fact the forthcoming Dell Streak 7. Let’s also not overlook the fact that Streak Smart called out case designer, Vaja, for listing a 7” Streak on their website.

From the Engadget leak and the WiFi certification, we know that the Dell Streak 7 will be a 7” Android device that functions as a phone as well. It’ll also have WiFi b/g/n and a Gorilla Glass screen. The commercial concept also mentions a “blazing graphics card for on the go gaming” which could indicate some Nvidia Tegra integration, but could also just be marketing speak for “Look, it plays games!”.

the original 5” Streak was already considered huge for a phone (and hasn’t quite taken off)… We’ll have to wait and see how people react to Dell expecting them to use a 7” device as a phone. Chances are, we’ll get a look at this device at CES 2011.
