zalbard: Oh, it will. Very few though. big volumes sold of 95% from top performance imho might result in more profits for vendor then very small volumes sold of niche "the top" rad.
If you notice - when newbies here on forum ask "what rad" almost always it's swiftech's MCR, not other existing "top" rads. And if this won't perform better then any other out there, it will loose even that niche, i highly doubt modularity will be enough to convince buyers except ones aiming only for bling in their builds.
Second example - do you think that aquacomputer sold many silver Kryo waterblocks? Even though it is The Best cooling wise (copper one already was, so this most probably will slightly win over that .. at 4 times the price).
