I was wondering (if its possible to know) how often they update the MacBookPros?
How long does the current generation of MacBookPro go up before a new model replaces it? How long are the cycles in between models? 6 months, or twice a year?

That seems to be the best source for questions like this.

the MBP was only just updated, now is the right time to buy

As Andy says, new MacBook Pro's were recently introduced (on February 26:http://www.forbes.com/2008/02/26/apple-macbook-intel-tech-intel-cx_bc_0226apple.html)

I just bought my MacBook Pro a couple weeks before that, but honestly I don't feel like I missed much. Aside from a very slight speed bump, the most compelling upgrade seems to be the multi-touch trackpad (like the MacBook Air has).

But the point is, I needed a MacBook Pro two weeks earlier, so I chose the model which best met my needs and bought it. Waiting for the "next big thing" is a losing game IMO. If you need a computer, buy it. If you can wait, wait. It's a given that the next model of any computer will be faster/cooler/better/cheaper so it's always a good idea to wait until you really need to upgrade.

Exact same position as I, Boyd, I bought one 1 or 2 weeks before the upgrade, and very pleased. I also needed it THAT day, so.
Very pleased too (now made the switch to mac and FCP officially).
