It would be odd to have 215 and 255 hp ratings for just 1-1.5 years. There will be a change to 323i and 328i, but I think the current 255hp rating will stand with the addition of the 335i and its new engine.

With the addition of the 323i and the future 1 series introduction to the NA market, BMW seems like it is serious about going after the whole 20k price range. I don't see any holes.
