So Bryan has reviewed a preproduction version and he claims that it will be better with a 2x TC than the original was without a converter. The charts back him up.
That said, I'm a happy owner of the mark I version of this lens. I just got today the 7DII and was out playing and got this pic w/ the 400 and a 1.4x:

If it's really true that the 400 II is sharper with a 2x (2x!!!) than the 400 I, yeah, I'm buying that lens.
Anyone have some real data or are we just waiting?
