I am waiting as well. I think the new AMD parts will be worth waiting for and if they aren't then I'll probably continue to wait for the next Gen Intel parts. Current Gen AMD is very good, but I am really looking for a release with significant IPC improvements because between this gen and my 6th Gen Intel, that hasn't improved enough to make it really compelling. Cores have increased, but IPC has grown stagnant for the most part.
Plus, even given the good performance on Intel parts, the power consumption is ridiculous. I think Zen 3 will give us same as Intel performance with much lower power consumption but only time will tell.
