Looks like they've made some much needed ergonomic enhances to the battery grip. The old one was a brick. Better have that multi controller we saw in Africa. If so it's looking like every dream I had for the Mark III is coming true. Well, duel CF would have been nicer but I'll take the CF/SD compo anyday over just one CF. Redundancy is everything.
And people get over the price! If this cam is indeed $3500 for the body only, about $800 more than the MkII, than just save for an extra month or two. We're getting a mini 1DX for half the price and that's a big deal. I'd pay a bit more.
