That's what www.jalopnik.com
seems to indicate, but I haven't heard anything anywhere else pertaining to the LaCrosse lately.
I hope it' s correct, though.
I've come across it on other sites in the past regarding a LaCrosse debuting at Chicago '08. I hope this doesn't disappoint; I know the current LaCrosse is on an aged chassis which basically premiered in MY1988, and the new generation is to be an a brand new Epsilon II, a follow up to the current Epsilon (the new Malibu and Aura are on the long-wheelbase version of the current Epsilon), but I hope it isn't shrunk or humbled down in comparison to the current LaCrosse, especially now the the current LaCrosse has an upgraded Super edition.
It could also be possible that Jalopnik by error steered us wrong on the LaCrosse premiere.
