I plan on purchasing a 2013 MBP when they are released. However, the rumor mill is suggesting all the MBP models will be retina this year. If that's the case, so be it, but if non-retina is an option, I will go with that. Either way, I would be buying the model with the dedicated GPU. I want to know if people play WoW on the 2012 rMBP with little problems, and if there are problems, what are the main problems? I'm currently playing on a 11" 2011 MBA, so anything will be an upgrade. WoW, and maybe occasional Mac Store games, will be the only games I play on it.
