I think only big difference to buy now or later would be if Apple starts using Nvidia CUDA Compatible Graphic Cards. There are some rumours flying next MacPro will have Nvidia CUDA Compatible Graphic Card as default so maybe high end iMac could also have one? Just wild guess. I have absolutely no information. Anyway this would be big thing for at least people using Adobe Premiere, Davinci Resolve and some other softwares.
