Firstly, I disagree with the OP. I just don't see that Apple would not update the MBP with a better trackpad and Penryn in a few weeks. It's not a major update, and I'm certainly not gonna be upset that I didn't wait 6 months to get this model.
However, despite what people say, there is some overlap between the MBP and MBA. This is because not everyone in the world falls into a designated category. For example, I have a friend at Uni who is doing lots of computer programming subjects. He has an old PC desktop, and wants an Apple notebook. But the question is, does he buy a MBA, going for long battery life, and portability, and continue to rely on the old PC for games and storage, or does he buy a MBP, and trash the old PC?
Then again, this is not a reason why Apple should delay the MBP. Because whichever he buys, Apple will still get their money, and he'll get a great machine that will undoubtedly make his next purchase also a Mac.
Now, although I reckon this update is going to be pretty pointless (Merom update from Yonah) and I think Apple could definitely get away with waiting for Montevina (which will make a worthwhile update) they won't. Although they tend to fail dismally with GPUs, Apple seem to take pride in using the best CPUs available. It might take them a few weeks/months/(almost a year ie. Mac Pro) but eventually they get there, and they don't often miss a step. For this reason, so Apple can tout their use of cutting edge 45nm technology, I say the MBP will definitely be coming in a couple of weeks.

Im very interested in this....
Expect Montevina MBPs around June. Expect better wireless, possibility of Robson Flash Disk technology version 2, DDR3 800MHz RAM, and a better GPU. And slightly better CPU.
I think everyone is going to be very underwhelmed with this update. The next few updates look excellent though. Montevina, then Nehalem (Core 3) early next year... Quad Core MBPs next year...
