Im really looking forward to this. Regardless of what other people think, i actually really liked Shadow the Hedgehog, Sonic 06 (no matter how much i felt like snapping the disc at times) and Unleashed (yes, even the werehog). On top of that, i prefer the post ShTH voice actors, but thats for another topic, my point is, i think sega are still going strong and this looks really promising.
The only things about the series that i didn't like were the Chao Gardens, Tails pre-ShTH voice acting (and to an extent, Rouge and Shadow's), and Sonic Advance 3 (a personal dislike). I'm also a little annoyed at how Sonic Heroes (and in a way SA2) stripped the characters of their uniqueness and labelled them speed, power or flying, as well as the same levels in the same order for every team, but once again, i digress.
This looks real fun, a sort of nostalgia thing which hopefully will have a good injection of creativity (I'm looking at you, Eggman bosses from Unleashed!). As for the inclusion of the homing attack, fine, as long as it is somewhat useful (i never recall using it much in the rush duo) but not over used.

Do you refer to the images of what might be gameplay hidden in sonics model? If so, AWESOME! Blue Nocturne likes the zipline
