The One series should have stopped after the first. I loved Hopkinsville stuff, but all things being fair and honest, there were numerous sketchy releases after about the original Vortex, Apex, and Cat series. Heck, they've done 3 versions of the Puma which wasn't that great to begin with.
I've been hoping for Wolf series, Apex series ( at least the Reflex), Omega series. Granted most of those cores are no good based on current rules.
Columbia could have also gone with Piranha, Quake, or Boss series and would have made a lot of people happy.
