Well I did think it was odd that they extended the rebates on a bunch of lens from being the Sat. before the show till the beginning of Feb. hints at maybe a Canon reveal right after the rebates end.
In a related note, Monday the 9th having been a National holiday in Japan (think hordes of girls in kimonos who are all 20 years old storming shrines throughout japan), I didn't expect any announcements yesterday.
From some of the posts here of interviews with Canon, they keep re-iterating that CES is a consumer show I had expected new non-L/EF-S lens to be announced. Still have my hopes up that that will be the case. A new 50mm 1.4 would be nice as well as 30mm f2.
