When Apple finally puts Thunderbolt 3 on their macs, how will we connect our "old" Thunderbolt and Thunderbolt 2 devices? Do you think they will just release a simple adapter? Or do you think they will leave TB2 ports on their, and just ADD TB3/USB C ports? I have to assume an adapter is possible to make, as surely they couldn't make our TB and TB2 devices obsolete so soon. Pretty basic question, I know, but I'm trying to plan some future purchases.
