I'm having the same problem... don't know if i should buy 2010.5 or better wait for 2011

Does anybody know when BIAB 2010.5 for Windows was released (i couldn't find that out...)? I wonder how long it took them to bring it for the mac (mac version came out in july) last time...
and BIAB 2011 for windows was released in September, right?

Thanks for your help!
