Its tough to say. Apple likes to upgrade its products regularly. If they want the Macbook Pro to stay competative, stat-wise with other PC manufacturers out there its going to have to step up the macbook pro soon.
Penryn, eSATA, 512MB VRAM+new state of the art mobile graphics card, Blu-Ray BTO option, new current hard drive BTO options are the things that i'd expect to make the cut for the update in January. If apple just included these, it would really make the Macbook Pro the top machine on the market.
As for the other things: multi-touch trackpad, biometrics, black aluminum option, would be great, but its not necessary.
Redesigned power supply, apple remote and lid are pretty much things they have to fix because their either defective or outdated, (Apple wants to replace all the PVC in their products ASAP. That means the remote has to become aluminium.)
And, i've said this before. Wouldn't it be cool if there was a holder that would hold your aluminum apple remote that slides into the express card port? That way you can't loose it?
Plus, i'd like better speakers if possible. I think there was even a PC laptop that had a built in subwolfer. How awesome is that idea!!
