Hi Y'all, apologies if this has been brought up before, but I am (like many) enamored with the new 5K Retina iMac. Definitely going gaga over that display. I do a good amount of photo editing and so it would be a great upgrade for me (have an older 27" iMac and rMBP15). The only thing about it is the 3TB hard drive. It sure would be nice to have more space than that. I was reading an article about the new iMac and it said that other than the display itself (a design and engineering feat, no doubt) not much of the internals changed. So, that makes me wonder if they'll do a little refresh sometime soon with the option to upgrade to a larger internal HD. And yes, I have multiple external Thunderbolt drives, RAID, etc. etc. and they are great for backup but an at least 4TB internal drive would be fantastic. Thoughts from anyone who follows these upgrade cycles closely? Speculation?
