Not really, a 1080i signal can be de-interlaced to produce a 1080p image anyways which is how the majority of current 1080p TV's work.
I'm assuming there is a difference between what you describe and a native 1080source/display. Anyone care to enlighten me on that?
Sis-
I was actually looking forward to the dual hdmi!!!! I wanted an HDMI connector to the tv and a dvi connector going to a moniter where I have a wireless kb/mouse parked. Silly I know, but I'm dissapointed about the ommision.
