It seems that rumors of the Canon 1Ds Mark IV just won’t go away. The latest word from Canon Rumors‘ sources proclaim an October announcement – with availability in 2012. Frequent spec rumors include a 30+MP sensor and high frame rate.
With no solid leaks or consistent rumors, it’s all still guess work at this point. With no new pro DSLR from Nikon so far this year though, there’s no new competitive threats to the 1D Mark IV or 1Ds Mark III.
There’s been a lot of speculation that the Japan earthquake has delayed both Canon and Nikon’s new products; however, that is still speculation until we get word from the companies’ mouth one way or the other. And that’s probably not something we are going to get – both Canon and Nikon rarely tip their hand until they are ready to proceed with their own marketing plans (leaks notwithstanding).
