you know i almost prefer the MBP's to come out later than earlier.
looking at it this way... if the MBP's come out at the end of October/early November, it'd be 10 months since the Rev. A MBP's were announced, and I doubt MBP's would be upgraded at MWSF (2 months after), which would be nice of course. A 1 year delay between upgrading MBP's means higher resale value for MBP owners (it's not always being refreshed), and surely would mean a case redesign or something spectacular.
Then again, Santa Rosa is slated for April 2007. Looking at its
specs, it seems perfect for Macbook with its integrated graphics. Apple just wouldn't upgrade Macbooks with the Santa Rosa platform without upgrading the MBP as well.
And also, benchmarks between Core Duo and Core2Duo show that the upgrade isn't very
significant. (especially with games -- practically 0% increase at all).
