Yes it does. The Bionic as we know it will be launched. There may be slight spec differences, but the design will be the same.
Here's what I expect to see changed:
-OMAP dual core instead of Tegra 2 (maybe Snapdragon?)
-1 gig DDR (doubt DDR2 will make the cut)
-Perhaps a different power management system
Sorry, no way they retool a motherboard for a different CPU and launch in q3, just isn't gonna happen with a large company like Motorola. This has to be something they already have in the testing phase to make that launch timeframe.
