Any con of just using hdmi vs mini dp?
Some of the resolutions that I use over HDMI are limited to 30Hz, fine for fairly static work (database, spreadsheet/workbook, word processing) but really annoying for more "active" tasks (drafting/illustration/video work).
I run a small company and, therefore, have vendors trying to sell me product every day of the week - generally. Almost all of them pulled back after the recent TI chip incompatibility bit that cropped up - it's not just a Mac thing - but all of my vendors recently offered the "wait until CES" bit in the past couple of weeks. Yes, they want to sell me product (and many of my peers, who I talk with regularly...), but they also want repeat business. That all of my vendors are now offering the "wait" caveat, and what I've read in forums like this one, I'm waiting for CES.
My only comment regarding the follow up reference to the Club 3D product - it reads like a nice product, but none of Club 3D's DP-related products have been through DP.org's certification process but they're asking premium product prices. Not-certified DP cables and adapters have fried motherboards and GPUs in several of my workstations and two of my personal Macs (including my current late-2013 rMBP, now rocking a new motherboard/display/battery because of that same issue but covered under warranty with Console logs to show the cause of the failure), I'm not buying any DP-related products that aren't on that DP product portal, ever, as I've learned that lesson.
Regardless, until there are some newer docks and hubs as you've indicated in your OP, HDMI should suit your workflow fine until the new chipset finds its way into new products. Cheers!
