Cover feature in this month's issue of Empire confirms a few things, with director Colin Trevorrow saying: "I think anyone concerned we've pussified the raptors is going to be pleasently surprised."
Feature confirms that the final act features a raptor attack on the labs (with a mix of a physical raptor model and motion capture) and hints (barely though) that there will also be a Rex/Hybrid showdown. and something else that sounds great but which I'd much rather had been a surprise. So I won't say what it is here.
Another preview also confirmed that the Rex is the same as the one in the original film, with the director adding that "this movie is her Unforgiven."
All in all raised my optimism a notch, but I'm still concerned about there being too much CGI.
