Lutz certainly wasn't lying about GM having a lot to show off at the auto shows. Even what they presented to the dealers is apparently only the tip of the ice berg.
We'll see the new Malibu, the heavily reworked STS, the all new CTS, the production Enclave, and the LaCrosse Super.
We'll also likely see the "concept" RWD Impala, the next GTO, the next Grand Prix (ie the new Commodore from Holden although I think the sheet metal might change a bit on this one because it is supposedly going to be manufactured here), the next Astra (made for both Opel and Saturn), and likely a few more surprises thrown in (think a new lineup of engines that will blow your mind).
