I REALLY hope this is true! This game was the MAIN reason I bought a 3DS in the first place. It was the deciding the factor between buying and waiting when it launch last year!
But I somewhat doubt this is the case. As far as I'm aware PLvsAA hasn't even gotten a Japanese launch date let alone western one. That and the fact that Level 5 always take forever localising their games. Their next professor Layton game is set release I think autumn this year in the west, even though it was a 3DS launch game in Japan. Also I don't they would want to release games in such proximity of one another. May decrease sales overall.
