I'd be very surprised if they sell enough to make it worth the cost.
Lets face the facts. Phase change cooling is incredibly enthusiast-focused, far more so than normal watercooling. Considering the fixed copper tubing imposes rather strict choices when it comes to motherboard and graphics card compatibility it's hardly "bringing phase to the masses" (I know they never said that, but thats what they are going for).
Theres also the fact of cost, have you see how much these cost? £500+ is just extortionate for a 10*C advantage over water, anyone who's serious about cooling would spend the same amount of cash on a proper unit.
Bottom line is, if OCZ couldn't make it work with the Cryo-Z, my expectations for Thermaltake (a company who isn't even taken seriously in the water cooling community) are LOW.
