The other thing to remember here is that WotC knows they are going to annoy people in the short term because of what the CB is not able to do from the start... but in the next month, two months, three months etc... one by one those annoyances are going to drop away as new functionality is added. And in just a little while, we are all going to forget just how angry we were at this point in time.
I mean... is anyone out there still angry about the gnome, half-orc, druid and barbarian? I seem to recall a whole heap of piss and vinegar aimed directly at WotC when it was revealed that those four things were not going to be in the first Player's Handbook. We had all kinds of people going on and on about how they won't be able to upgrade their character to 4E, that if this is how WotC was going to treat them then they don't deserve their business yadda yadda yadda.
But then, nine months later... once the PHII got released... we haven't heard hide nor hair of any complaints about that situation anymore. And the same thing can be said for the CB as it stands.
WotC is going to take the slings and arrows from us messageboard folk for however many months it takes before they reveal the additional CB support or additional tools... and just accept the insults in the short term... knowing full-well that in six(?), nine(?) months time they are going to announce the release of X or Y or Z and suddenly all the caterwauling virtually die out.
