The game is out by the end of May (26th) and will have virtually no competition unlike Killzone 2 which was sandwiched between Street Fighter 4 and Resident Evil 5. I think these two games took away a big chunk out of Killzone 2, especially RE5.
I don't think it will have a bigger opening but it will sure have longer legs and eventually outsell Killzone 2.
