Possibly they discovered that each release resulted in a torrent of pissing and moaning about the performance/features/eye candy/shoddy support/can't do this, can't do that, broke my ..., USB blah blah blah, coherence isn't, 3188 broke my beta boot camp..., Parallels support sux complaints. Better to fix what ever's broke quietly in a controlled environment than to publish your warts for all to see and experience. And it really makes sense. Their public beta releases in the past gave too much goofy code to too many really stupid people. Not everyone should be/is qualified to be a beta tester. I hope they've learned at least that. And mixing beta with released code as they have done from the beginning has been a disaster. Fixes for whacked beta/RC code were being applied to released code, or to previous/older beta versions and it was ridiculous, chaotic, and unprofessional. And it killed a lot of good will/first to market momentum they had built up. Accept the silence as a better, more mature march toward excellence. At least until you know better.
