New Mac Pro help for 4k camera

Hello,
My office will be moving to 4k production his fall with the arrival of the new 4k production camera. I'm currently up for my biannual computer upgrade and I'm looking for some help on what will be the ideal setup. I know there are rumors about a new Mac Pro but unfortunately I think I need to make my order by the end of the month. I might be able to wait if we get some answers from Apple soon. We will not be going completely 4k right away. I'm sure I'll continue making 1080 videos until I feel ready to go with 4k. Basically I need help figuring out what would be the best setup for me. The current Mac Pro or the new iMac? What is the recommended graphics card for best workflow? Any information you can provide is greatly appreciated. How much memory? Good monitors for 4k video? Processor? External Hard drives?
Thanks!
