It had been expected that Canon would make some announcements today, and they did; unfortunately many were hoping for a replacement for the 5D Mark II, instead Canon has announced two new low-priced DSLRs and some new lenses:
Canon T3 / 1100D for $600 with a kit lens you get a 12.2 megapixel CMOS sensor, a DIGIC 4 Imaging processor, nine-point autofocus system and a 63-zone dual later metering system. BUT, full-motion video only goes to 720p; 1280 x 720 resolution.
Canon T3i / 600D for $800 body only, looks to basically be a minor upgrade to the T2i; for video shooters it notably adds a tilt-swivel LCD.
It doesn't appear to do anything really new or different in the video capture department when compared to the existing T2i or 60D, though we'll probably have to wait for the reviews to confirm this. About the only thing that can be said for it is that it might make people thinking of buying the 60D for video - because of the tilt screen - look at the T3i instead.

EF 200-400 f/4L
Perhaps more interesting for video is the EF 200-400mm f/4L IS USM EXTENDER 1.4x, which they have announced as being "in development" and will be available sometime this year.
It has a built-in 1.4x extender - not sure how that works! - that increases the focal range of 280 – 560mm.
