release week will probably be bigger for fable2 cause its an existing ip, over time i think lbp might sell more software depending how much advertising and media coverage it gets.
on hardware sales i doubt that fable 2 will do too much, lbp with bundles in eu and japan should boost hardware there (especially in japan with 80gb release) but in the us without bundles i doubt it will do too much (but it should stop the slow decrease in ps3 numbers and give it a small bump upwards).
anyway these 2 games are the starters for the bigger releases after a rather dry period (besides the sport games there was not much in the last months) so we might see bigger boosts than expected.
