I have obviously read the same rumors as everyone else, but still looking for opinions. Currently have an older iMac and a 2013 MacBook Air w/256 ssd. I need more hard drive space for HD video editing. Debating between a 27" iMac with the 2tb fashion drive, or a 15" mbp w/256 ssd then getting an external thunderbolt drive for file storage. I don't need it urgently. I don't foresee any breakthrough updates with the next revision, and doubt the processor bump will affect me a whole lot. I just would like to be able to drive an HD display with it eventually. So... Current high end iMac, current mbp, or wait for new mbp?
