Like you, I was curious when 2009 came to a close and the Tour, Curve 8900, and the Bold 9000 are still sitting with older OS builds.  The folks at CrackBerry reached out to RIM yesterday, and received the following response:

RIM began rolling out BlackBerry OS 5.0 late last year through our carrier partners for supported devices, including the BlackBerry Bold 9700, BlackBerry Storm and BlackBerry Storm2. We continue to work with our carrier partners to make BlackBerry OS 5.0 available to users on new and other supportable in-market BlackBerry smartphones.

So while RIM held up their end of the bargain, we’re waiting for the builds to pass testing (known as “technical acceptance”) at the wireless companies.  If you’re still upset, be sure to speak with your respective carriers and let them know what you think!
