Interesting. I found just the opposite - my 100-400 @400mm beat the 300/4 IS + 1.4x II (and that seems to be a common theme from testers). That was with AFMA dialed in on both - without AMFA, the 100-400 would miss a bit at 400mm leading to reduced sharpness.
It's funny - you think something is razor sharp, then you see what razor sharp really is, say going from a 100-400 or 300/4 IS to a supertele prime.
Regardless, I expect a new 300/4 IS II would be noticeably better than the current 300/4 or the 100-400. I'd also expect a revised 100-400 to noticeably sharper, and I'd take that over the 300/4 II.
