Then you have faith and strength where I do not, wnxgenral.
I'm in a situation where I more or less need to get some sort of working laptop ASAP, and the current generation MBP would suit me just fine, but I'm doing everything I can to hold out for the refresh in hopes that: A) the new GPU won't be plagued by the "nVidia Heat Cycling of Doom," B) the CPU power will be boosted, even slightly, since I often tend to max out CPUs in my work, and C) the price will go down. If the case is redesigned and allows for user serviceable hard drives, then bonus; 320gb @ 7200rpm with no risk of voiding the warranty, here I come. Yeehaw.
At the same time, if there is, indeed, a case redesign, then it's almost certainly going to suffer some Rev A Troubles. Do I really want to deal with that? Not especially. Plus, supply will be low for a while, meaning some inevitable bloodshed in my attempts to procure one of the new lappys. This means that I'm really, really having to fight off the urge to buy now and just be done with it. Long in the tooth or not, the MBP is still a damned sexy design, and its power is still up there compared to other laptops. At the same time, no one really knows how widespread the current GPU issues are, and whether anyone buying the last (er, current) generation is really just buying admittance into a future class action lawsuit. Do I really want to deal with that? Not especially.
So I commend you for taking the plunge at this tumultuous time. Me, I'll be back in the corner, biting my nails and frequently weeping, looking up every couple of days to see if the announcement has been made by Apple and incessantly repeating "Monte is coming, Monte is coming, Monte is coming..."
