Haha, you will be pleasantly surprised by the white 600T and 650D performance I hope.
We're definitely looking at aircooling - to a degree I think most of our competitors can't or don't. It takes a long time to develop a case - the 600T was in development for over a year before it launched last summer. The 650D was a bit quicker because it used the 600T skeleton.
But some of the testing we're doing is showing that the brute-force method of cooling (tons of fans) is one valid approach, but another approach might also be worthwhile. Our goal is to have products for each customer at each price point, but we've only got 3 cases in the market right now (four if you count the white 600T as a separate case) compared to our competitors with 20 or 30. We have some growing to do.
We have stuff launching later this year that's been in development for over a year already, and I already have stuff on the roadmap for 2012 and 2013. Including refreshes of cases we haven't even launched yet.
But this is how the business has to work.
I launch the 600T, look at your feedback, and roll that feedback into future cases. So the cases launching later this year already incorporate feedback I've gotten from this very forum on our other cases. Stuff like "let me mount 120mm fans in the front" or "make it out of pure awesome" are on the list.
