Another question left up in the air is whether the G2 would be sporting a version of HTC's Sense. A product listing for Walmart recently suggested that the phone would be launched with Android 2.2 and the manufacturer's Sense UI. However, T-Mobile has already announced that this would be a "with Google" phone and those testing the device have stated that it is running stock Android 2.2. Considering that the father of all Android phones, the G1, was running stock Android, the G2 would most likely follow in those footsteps.
As a high-end model, you would expect the G2 to be priced as such and while no details have been announced, we would imagine the recent $199.99 gold standard pricing that we have seen on devices like the Motorola DROID X and DROID 2, BlackBerry Torch, and both Samsung Galaxy S variants launched by AT&T (Captivate) and T-Mobile (Vibrant). Speculation is that the G2 will be launched late next month.
