I just got word from a reliable source that there will be no new Canon DSLRs announced in 2011. Bummer.
Note that this person hasn’t been flat out wrong before. A day or two off on dates on a couple of occasions, but never out of the ballpark, so I feel pretty comfortable with the accuracy this rumor. That said, this is still a rumor and should be taken as such.
No other real hints of what’s next – other than some recent patent applications for radio-synced camera bodies and TTL flashes with radio triggers. However, if Canon manages to get these two features in its next camera, I think it will be well worth the wait.
