Apparently somebody has hacked the 550d/t2i to shoot 4K, will find out tomorrow (1st January) for sure if it's real or a hoax, interesting stuff. If true might force canon to bring to Market a 4k dslr faster than otherwise. http://philipbloom.net/2010/12/30/shoot-2k-3k-and-4k-on-the-canon-550d-t2i-coming-in-2-weeks/
