Two questions about BioShock 2

[LegendaryOpponent]

1)      Do you think BioShock 2 on PlayStation 3 can outsell Killzone 2 (we’re talking about first-week sales here)?

2)      Halo 3 sold 3.82M in 4 days. Can BioShock 2 (X360 + PS3 combined) outsell its first week? Oh, and I mean Xbox 360 version, PS3 version COMBINED.
