I would be ok with the X-Men showing up if Rachel ended up reading one of the Illuminati's minds and figures out the whole event is Cap's fault.

There should not be too much b***hing about this for two reasons:
1.) This was PAINFULLY obvious, since Whedon introduced Thanos as his real Big Bad at the end of the movie, so they're probably trying to synchronize the movie-verse and print-verse as much as possible.
2.) The X-Men seem to be barely involved, which is incredibly wonderful after the shite that was AvX. I'll take the X-Men having a 4-issue irrelevant tie-in over being part of the The (Annual) Big Event that Changes Things "Forever"
oh boy, here we go...
I specially liked this part,"grandest Marvel Comics event of all time,"
