New Flash system in late 2011/early 2012
Canon going radio trigger wireless?
That's the latest bit of info sent this weekend.
Canon will release a new flagship flash, as well as a replacement to the 580 EX II.
The flagship flash will have new features unseen in a Canon Speedlite before. No word on whether or not it would have some video features.
The ST-E2 will remain current, however a new radio trigger will be launched alongside the flashes.
First time submission, so take it with a grain of salt.
