There is a report from some insiders that Canon is currently testing cameras in the 24mp and 25fps range (could this be canon's much rumoured HD movie mode for photo journalists?). As I thought, Canon will be replacing the 1d3 as soon as possible. An announcement could be for Photokina for an early 2009 release.
Hopefully the camera(s) can autofocus.
Conflicting reports about a 5D replacement? There is at least one insider reporting there will be a 5D “related launch” at PMA.
