So you'd say the 5D III and 1 series don't really need their extra AF CPU's its all just marketing BS? After all, 5D III and 1D X have digic 5+ like 70D, which you say has more than enough power.
I'll grant a single digic 5+ may have more than enough grunt to match dual digic 4 + AF CPU, but I suspect there's more to it. Maybe they have improved the actual AF sensors on the 70D and improved the algorithms.
I'd say we have no idea- both cameras are older designs, and again, we don't know what 'Digic anything' actually means, other than that it's a marketing bullet point. But if I had to guess, I'd say a little of both- the 'Digic 5+' doesn't have to actually be more 'powerful' than the cluster in the 7D, as it has less AF capability to manage overall, given the decreased flexibility in the 70D; but there's little doubt that the algorithms used to manage the AF module have been updated, as could the module itself be 'updated'.
Either way, it works, which is the point I think .
