Canon announce new Hybrid IS system
Canon has today announced the development of a new Hybrid IS (Image Stabilization) system that compensates for both rotational movement (tipping or pitching) as well as linear movement (caused by shaking, or vibration). Existing anti-shake systems reduce blur caused by horizontal and vertical (linear) movement only. Canon say the new Hybrid IS system will be introduced in a DSLR lens sometime before the end of this year.

My own thoughts are that we'll see this implemented in a new EF 70-200mm f/2.8L first. Alongside the 16-35mm f/2.8, this lens type is by far the most important and widely used among professional photographers and is often showcased by manufacturers. Shortages and rumors of an update have been circulating on this lens for sometime (as have that of the Nikon equivalent, who won't want to be seen to lag too far behind again).
We will then most likely see the systematic updating of every current IS lens, and after starting with the 70-200mm f/2.8 swiftly moving on to the super telephotos: 300mm f/2.8, 400mm f/2.8, 500mm f/4 and 600mm f/4. Most of these lenses are several years old and are due for updating (improved optical formulae, Sub-wavelength Super Spectra Coatings, lighter weight magnesium alloy barrels and possibly improved USMs), the 300mm f/2.8L especially (it's a 10-year old design). I wouldn't expect to see the 200mm f/2 or 800mm f/5.6 updated for the time being.
We may even see the long rumored EF 180mm f/3.5L IS macro and EF 24-70mm f/2.8L IS, if only to stop the banter about Sony's IS system being available with the Carl Zeiss 24-70mm f/2.8 and 16-35mm f/2.8 (it's built-into the A900 and A700 camera bodies). Who knows, the Hybrid system could find its way in a new EF14-35mm f/2.8L and maybe even the way overdue EF 150-600mm f/5.6L or smaller EF 200-400mm f/4L. I doubt it somehow but would certainly like to think so.
