I was told that the 500 AP support will come with the next major release of code (7.0?). Then again, given that the initial controller hardware buy-in is so low (it's the same hardware no matter what the initial AP count), small sites may find that two 5508s, with 250AP each, more appealing than one monolithic 5508 with 500 APs.
Also of interest in the 6.0 code... While the 5508 can download code to 100 APs at a time (traditional upgrade method), there is a new feature in 6.0 which allows for pre-loading of the AP code. Basically, you load 6.0 in the WLC then tell the APs to download the new AP code (they stay connected and up). Then, when the controller is rebooted, the AP's swap between the older IOS image and the pre-loaded new IOS image. Should make controller/AP upgrades much less disruptive.

Through a code change this number was reduced to 250 because of some errors when approaching 500, but the beta hardware had a 6 core cpu, not the 10 core that's in the final version.
