As for a source, wanting to have the FF in the same universe as the X-Men is pretty much the only information that's been released about the FF reboot, so a source shouldn't be too hard to find. But you'll also find it in the quote I used from Millar: "Fox have said they want to build a cohesive universe..."

I agree that it's kinda weird to put an old franchise with a new one, and that X-Men and Fantastic Four probably aren't the most compatible pair of teams to make a universe out of, but I'm hoping that they look at it like they're sort-of leaving the old trilogy and Wolverine movie behind, and starting a new direction with First Class. Otherwise, I do think that a reboot of the X-Men series would fit better with a reboot of FF, and by extension, the MCU and ASM.

And I totally agree with you on how they should treat FF. However, I think that if a deal was struck between Marvel and Fox and Sony, FF may reference mutants a little, and that could be as far as the connections between them go. But they could have stronger ties with the Avengers or Spider-Man, as could the X-Men, and consequently create a bigger Cinematic Universe.
