How about an Usher S-525 or X-616 to tide you over until they release the matching BE center? I'm using an S-525 center with CP-6311 for fronts, and they seem to match just fine for HT after an Audyssey calibration. I don't have room for the X-616 otherwise I would have probably gone that route, but I'm content as is. 2 channel music is more important to me anyways.
The S-520 would make good surrounds but they wouldn't be matching. Not a big deal unless you listen to a lot of multichannel music, IMHO.
