Some interesting engine choices coming for 2011 too...
Some of this info was in Mustang Monthly this month too
Looks like no EcoBoost V6 or V8 next year.
Ford is supposed to release all the info next month.

"We've already heard that the 2011 Mustang is expected to get a pair of new engines--a 3.7-liter Duratec V-6 engine to replace the existing 4.0-liter unit in the current base Mustang. Power is expected to go up despite the drop in displacement, from 210 horsepower to a whopping 315 horsepower. That's about even witth the curren't 4.6-liter V-8's output in the Mustang GT, so Ford is upping the performance there, too, with the new 5.0-liter Coyote V-8, rated at 400 horsepower.
Joining it is also a rumored twin-turbocharged, aluminum-block "Road Runner" version of the engine that could rate as high as 600 horsepower for the next GT500. We'll have to wait until December to find out for sure what Ford will be packing into the next Mustang, but if it's anything like the rumors, it's sure to be exciting.
Other major upgrades to the 2011 Mustang include an even more focused Track Pack, with a sharper suspension, bigger brakes and grippy Pirelli P-Zero Corsa tires, plus the return of the "5.0" badge."
