The current MacBook Pro design is probably going to be around until next year, but a minor update might be on its way in the coming weeks, according to a few factors that have telegraphed this kind of thing historically. Stock is low on many models, and more importantly, a few new items have appeared in Apple inventory listings.
The K90IA, K91A, and K92A SKUs almost certainly represent a minor update to the existing K9*s that are the current MBPs. A total redesign would have a lot more fanfare, so this is probably a spec bump. All the same, hold off on purchasing if you can, since you'll be getting more for your money shortly.
While there's no information on what the new models will have, it'll probably be a set of slightly better processors, a new GPU, Bluetooth 4.0, and possibly a new board to tie it all together. Nothing on the outside, and certainly no USB 3.0.
Price? No idea, but if they're adding features it's unlikely it'll drop. Price drops often happen as a consolation prize when there are no real updates to a line.
