Wide certainly plays into the strength of the EF-S mount, so that is certainly possible. Plus, summer announcements are about consumer products.
Patiently waiting. . .
Have Fun,
Well, if that full-frame rumor is true, they'd better have something in EF mount up their sleeve. I can't afford the 21 mm distagon! 
Actually, I hear that Canon's working on a full-frame ultra-wide or two to accomodate those that use their 1Ds II. I expect that the solution will not be cheap.
As for EF-S, that 10-22 really looks like a good lens. I expect an 18-70 EF-S USM lens to show up soon, also.
