Re: X-MEN: FIRST CLASS - Grading+Discussion **SPOILERS!**
Even if projected DVD/Blu-ray sales/rentals are say 75% of X-Men, that should be enough to commission a sequel. though I would expect it to have a smaller budget.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
