We didn't have a ton of details on the so-called HTC Ace when it turned up in a leaked roadmap last week, but a fresh set of rumors are now suggesting that the Ace is actually the Desire HD, which will reportedly pack a number of HD-esque upgrades over the standard Desire. That includes a larger 4.3-inch WVGA screen -- no word if it's AMOLED or SLCD -- and an 8-megapixel camera with 720p video recording. Other rumored details include Android 2.2, 4GB of internal storage, the same 1GHz Snapdragon as the current Desire and, perhaps most interestingly, talk of a "unibody aluminum design." Unfortunately, the rumors still don't include any actual images of the device, but there's still plenty of time for those to leak out before the supposed October release.
