RIM Secretly Working on a Blackberry Tablet?

Our good friends @crackberry have been able to come up with some interesting information regarding a potential Blackberry Tablet.  Their sources say that RIM has been ordering 8.9" screens from Asian suppliers for a wireless tablet that would sync with a Blackberry.  I for one am not excited about the prospect of this.  RIM needs to focus on Webkit, OS 6.0, and releasing OS 5.0 (officially) for all supported devices.  What are your thoughts on this?
