From a mixture of sources (including Canon Rumors and Northlight), Canon should be holding announcements on February 9th (not January 9; it would coincide with the middle of CES, highly unlikely thus for a new model to be released. However, due to translation problems, Canon Rumors initially posted under January 9. It has been rectified, and they have received confirmation that the latter date is more accurate.)
– several PowerShot cameras, including high-end IXUS or ELPH models
– a Rebel DSLR (ie, xxxD or xxxxD; Camera Tech assumes an upgrade to the 1000D, be it a 1500D or 2000D, depending on model names)
– possibility of a second DSLR, including a 60D or 1Ds Mark IV; possibly both, but unlikely
– if the 1Ds Mark IV is launched, it is most likely to be launched with some lenses
The only lens that appears to be likely is a 60mm f/2.8 macro to feature an update, giving it IS. Patents were seen in December, 2009, which indicated the 70-200mm f/2.8 IS II (recently released) as well. The patent diagram is below (image CR):
