There is a quite reliable source indicates that the new EOS body will having a brand new processor and it is not the digic5 appears in the powershot s100 and sx40. Anyone beside me hearing this news also?
Well the EOS line will not have the DigicV as it is in the S100. The DigicV in those cameras is limited to fit the uses of the camera. DigicV in the EOS cameras will be fully powered.
So I guess in some since you could be correct.
I doubt there will be more than one Digic5 processor, too costly to design and manufacture different processors. But yes, via firmware, some features could be disabled or slowed down but unless Canon has some big surprise for the world, there are no new "magical" image processing techniques that would only be added to the new DSLRs.
