LittleBigPlanet arrives on the PS3 this October. The PS3 install base should be around 16M. I predict software sales of:
NA - 250K
EUROPE - 200K
JAPAN - 70K
TOTAL - 520K
A good first week but nothing special. Legs will be terrific though, due to amazing word of mouth.
Hardware boost:
NA - 20K
EUROPE - 30K
JAPAN - 5K
Again nothing special. This should have a longer effect, rather than a big spike that lasts for a few weeks.
