AeroCool did not provide the prices of the upcoming case fans, but they shouldn't be too high, even though the spinners do have colored LEDs.
The SilentMaster 200 mm LED case fan series runs on, at most, 3W of electrical power. The current needs to be in the 9-12V range, something easy to accomplish for any desktop power supply
It is interesting to note that, this being a 200 x 200 x 20 mm fan, it could fit in cases with tighter inside spaces than other 200 mm fans, which have 30mm thickness. Then again, the extra 10mm would have given them a higher airflow.
Fortunately, these are case cooling implements, not CPU or VGA coolers, so they don't really need to be all that mighty. As long as they keep changing the air in the case, they are good, and they should have no trouble thanks to the 800 ± 200 RPM (76 CFM airflow).
Unfortunately, though the ETA is known (October 2012), the price is not.
