Both of these rumors today are on the weak end and use a bit if induction to get to their conclusion, but we'll throw 'em out anyways.
First, Nanapho.jp is reporting that the Trophy device used during the MIX11 demo (the one that puts its browser up against the iPhone and Nexus S) is not just the Trophy but the HTC Mazaa. What makes that interesting is during the rest of the MIX11 talks, whenever the gyroscope function was demonstrated it was on this Trophy/Mazza device. Nanapho gets the info via a Microsoft rep who evidently informed them.
Of course this still leaves open who the Mazaa is for and whether or not it will have the gyroscope on launch (we were under the impression that these were just modified Trophies for Microsoft for testing purposes).
The other rumor comes via Pocketnow who strung together a few pieces of info that suggests that Verizon is game for the HTC 7 Pro aka Sprint Arrive. The process is a bit of a math/transitive relation solving. In essence, we know there is a device being used with the ID MWP6885 (see our earlier coverage of new devices). There is also an FCC device that was approved called PC93100 which is a 7 Pro (confidentiality has expired). What links them together is a user agent profile called PC93-1.0.xml which, dun dun dun, IDs the MWP6885.
So if MWP6885=PC93 and PC93=7Pro (PC93100) then MWP6885=7 Pro.
Sure, it's a bit of a stretch but technically the logic works. Of course can Verizon actually get this out by the time anyone cares? That remains to be seen.
Update: This may or may not be the Mazza but they are new engineering prototypes that Microsoft is using in house i.e. Asus devices are out. Furthermore, these have Snapdragon and Adreno GPU with gyro sensors. Thanks to our source for the info.
