The 7DmkII will never ever have the ISO capabilities of a FF Canon (1DX, 5DMKIII, etc).. It's a great crop camera, but the ISO is about as good as the 70d. The weather sealing is nice but the 70d has that as well. The articulating screen on the 70D is also very useful (At least for me) as is the touch screen. You should compared them both together and see if the extra $1000 is worth it.
