The thing about ThunderHex is that while you can buy ThunderHex stock to use with it, you can make any hex shaft a ThunderHex compatible shaft just by turning it down a little on a lathe. You're not locked in to using Vex's shaft.
I'm excited about being able to do stepped shafts in one operation, using round bearings of varying sizes everywhere. Instead of making 1/2 hex, 1/2 round, 7/16 hex combo shafts, you could do 1/2" hex on one side and ThunderHex through the middle to the other side.
The bearings do cost more, yeah, but I'd pay $16 more per robot to avoid having to make stepped shafts, custom 7/16" hex broached sprockets, etc.
