Mac version is relased next week (supposedly, this is the 4th different release date so far). The PC version ships with the Xbox GH2 Xplorer guitar, not the same guitars that come with GH3. I play the PC version using BootCamp (didn't want to wait for the Mac version) and have a 2.4gzh C2D MBP with 4GB RAM and it runs no problem for me. Haven't tried hooking it up to the TV yet to see how that would work out. Best Buy and WalMart both had the Mac version for pre-order months ago, but now only show the PC version online. Amazon says it's already released, but ships in 1-2 months. I wonder if stores will replace the PC only version with the PC/Mac hybrid starting next week? If you have a console, it's probably better to get it for a console assuming you can find the game.
