I wouldn’t discount the video capabilities, there are a lot of professionals out there using DSLR’s for video production. Canon have long been criticised for lagging in video capabilities since it introduced the then ground breaking video capabilities of the 5DII.
From what I’ve read higher resolution gives more scope for cropping and stabilisation in post production, plus they’ve also introduced in body image stabilisation. Hopefully it will be as good as the hype, but I doubt it will be affordable.
