They already have two full size keyboards with your choice of Red, Black, Brown, or Blue switches and sometimes Green.. What is exactly the difference in board you're looking for?
Bang for the buck like QuickFire Rapid.
Whats wrong with the CM storm trigger?
Macro keys, I dislike macro keys. And uh...... price.
If someone ask you they want to buy a tenkeyless keyboard the first one in your mind will be most likely be QuickFire Rapid or Filco.
If someone ask you they want a full size board, most likely CM Storm Trigger or CM Storm QuickFire Pro will NOT be the first one in your mind.
Let's say QuickFire Rapid currently sells at $80 at most stores that I know. If they can sell QuickFire Rapid 104 at $85 in my opinion it will be able to bump them over the competition in terms of price and quality. CM Storm Trigger at $120 while it's nice but doesn't have the same effect as QuickFire Rapid's $80.

EDIT: wetto beat me to it but yes he's exactly right
Though sadly it might be like he said, since they just released TK so this will probably not happen unless they decide to remove QuickFire Pro from the lineup and replace it with the QuickFire Rapid 104/105.
