Canon Rumors has received confirmation that a new Canon body is being tested in Vancouver at the moment – model number unknown.
The same source also mentioned a 1Ds Mark IV release (or 1Ds MK IV) before the end of February.
A 60D, with high fps speed? A 1Ds Mark IV in the beta stages of testing?
Things remain to be seen. Keep a close eye out when watching the Olympics.
Note: according to Canon Rumors, this is ‘CR3′ source; their top tier ranked sources.
