Sonic Unleashed could bring back the speed.
The Sonic Knight game could be interesting.
And the RPG on the DS is shaping up fine.

So I think that there are just people who like to shoot fish in a barrel.

Sonic and the Secret Rings was actually a step in the right direction. Sonic and the Black Knight is being made by the same team. I actually think that this is going to be cool. Sonic will be around another twenty years at least. He'll kill all of the people saying that hes's dead with his new sword. Go! Go! Sonic!

 but the majority of people who buy that game buy it because of mario...not sonic, i wish it were vice versa. Sonic was such a great series...like megaman

They should just release a 16 bit sonic on wiiware,PSN and XBL and it would sell way better than any of the 3D ones.

I'm not so sure about that, a lot of the current Sonic fanbase were raised on the 3D games and they're usually the oens that buy every new console game religiously. Just the sight of 2D sprites would repel them like holy water.

So wut, Dr eggman won?

In order to make a decent transition to 3D, Sonic games ought to have more emphasis on careful precise jumps. It's not like 2D where the limited plane of movement make it very easy to just run and forget anything. If anything, a slower pace Sonic would be a good idea since it makes it easier for the player to make pin-point precise jumps, which is what platforming is all about.

Sales wise, no way.

Million selling games with "Sonic" in the title total out 47M sold.

By Generation:

13.95M of those are on the Genesis.

5.24M are on Ps2

7M are on GC

5.11M are on GBA

2.42M on DC

Total for generation: 19.77M

6.84M of those are on the Wii.

4.96M of those are on DS.

Already 11.8M

Sonic is far bigger now than he ever was in 2D, sales wise.

I've never cared for Sonic games, but he's not dead, not when they can still make a Sonic game that can sell 1+ million.
