According to NL, Canon 7D Mark II will arrive on Photokina, few days ago canonrumors [CR2] said “5D Mark III being announced around the end of March or early April 2012 ..”
Canon is also expected to update its entry level DSLRs such as T3 / 1100D and T3i / 600D this year, some of our new sources told us “Canon will Update 5D, 7D, T3 and T3i this year”, T3 name was unexpected, but I hope this rumor become true.
