Cooler Master has a successor to the QuickFire TK out, called the MasterKeys Pro M.
(The 'M' seems to stand for 'Medium" as the full-size is called "Pro L" and the TKL one is "Pro S".)
The big difference is the keycap sizes on the bottom row: The modifiers on the MasterKeys are now all 1.25u.
The keycap font is also nicer, more regular and not as gamer-y.
Otherwise the keyboards seems to exactly the same to me, but maybe there are updates on the inside.
