Next iPhone may possibly record HD video in 720p?

Okay, so Apple's iPod Nano doesn't exactly have the best video recording of all gadgets, but HD video is gradually shaping up to be a crucial feature to be included in next-generation devices.  Some hints have surfaced that HD video may just be implemented on the next iPhone.

If you've seen our post on the "N89" codename in the iPhone OS SDK, a tipster has just taken a look at the MediaValidator.plist file  - it reveals several enlightening stats: the maximum video width is up from 768 pixels to 1280, and the maximum number of pixels per frame is up to 921,600, resulting in a 1280 x 720 resolution. The device's AVC profile has been bumped from 3.0 to 3.1, too, which adds support for 720p.  Seems like everything points to the direction of HD video – thoughts?
