RIM BlackBerry Twitter App Not Arriving Until January 2010?

We recently received word that the Research In Motion designed Twitter client, which is being developed for all BlackBerry devices, may not become available until January 2010. It has been rumored to be releasing sometime in November. There have been a lot of very nice Twitter apps for BlackBerry's, but the one RIM is designing is said to shame all others. The BlackBerry-own Twitter client will have a 'push' feature for auto-refreshing. This will update replies and other users updates in real-time. If what we've been told about the release date push-back is true, well, we're quite sad as we're sick of waiting!
