A99 flash controller

Hi All,

I do plan on upgrading to the A99, have the A700 now, but the prospect of having to buy (waste) an expensive flash to act as a wireless flash controller is a little disappointing. Are there any rumors of some kind of a flash controller coming from Sony? Something like the Nikon Speed Light Commander, but at the price of a HVL-F20am would be great. Might even be an area third party manufacturers could exploit.
Thanks
