EPA estimate on the 2008 Hybrid is 27 city / 26 highway, according to an Edmunds Test Drive.
I can't find anything solid about the regular version... just that Toyota says the mileage is similar to the 2007 models, which is in the ballpark of 17/22. The Lexus RX 350, which is very similar in body style and weight with the same engine, also gets 17/22.
2008 pricing has been announced. See here:
