Little Big Planet + PSP = 2009?

Little Big Planet PSP

Little Big Planet must be selling really well because there are rumors of bringing it to the PSP sometime in 2009. The game could give the PSP a little boost in sales which have been lagging as developer’s have been developing on the DS more as of late. How much Sackboy will have to give up in order to be ported to the PS3′s little portable friend?
