All depends on whether your current computer a) meets the requirements of your university course of study and b) is still fast enough and usable enough not to drive you nuts in day-to-day use. If your answer to both questions is yes, then you might want to consider waiting a year. If your answer to one question or the other is no, then upgrade now. The current MBP has the requisite next generation technology with big improvements in speed and power across the board (Quad-core on the 15/17 inch models, Thunderbolt, SDXC, 16GB RAM expandability, 6Gb SATA, high-resolution screen options, and a substantially improved wireless card). As for the next MBP, given what Intel has promised for their approximately Q1/2012 processor update (built-in USB 3 support and a big reduction in power consumption and leakage due not only to the die-shrink but also the "3D" silicon technology), it won't be as dramatic as this one was. I suspect it will feature stuff like a considerable improvement in battery life, a further speed-bump but not revolutionary change on processing power, slightly cooler operating temperatures, USB 3, and perhaps replacing Firewire with a second Thunderbolt port, and who knows with the optical drive. In other words, it will be very good and probably a bit more pleasant and practical to use but perhaps not as big an improvement in speed and power as the current generation is over the last one.
Anyway, this version must be stable! I'm always a bit nervous getting Revision 1 stuff anyway!
