You are aware this site is called canon RUMORS yes?
70D... hmmm... let me think about this for 0.1 seconds. It doesn't exist, it may actually not ever exist. Sure canon will likely bring something new to the market by christmas (but wait, that could be next year for all we know), but does one want to wait that long? I wouldn't, I'd go insane.
Im glad I jumped ship and have a 7D and not waiting on nikon's replacement for the d300s! - Waiting?... .... Still waiting...
Its not worth it, just get something.
