From the Twitterverse: GM shows 3 Series-fighting Cadillac ATS, all-new XTS, 2012 Malibu

Tomorrow morning at 8:00 AM EST, General Motor's President and CEO, Fritz Henderson, will be hosting a webcast to update the public and the media on the automaker's turnaround efforts, during which Henderson is expected to make a new product announcement.

But ahead of tomorrow's shindig, GM is apparently hosting another event involving some of its PR team, around 100 members of the public and a few social media junkies. Tied to their smartphones, some of the attendees have revealed GM's new product plans and here are the tender Twitter morsels:

• GM unveiled a new Cadillac concept dubbed the ATS, a compact BMW 3 Series fighter that will be available in both coupe and sedan forms.
• The Cadillac DTS' replacement – currently named the XTS – will be built atop the Buick LaCrosse's underpinnings and will be available with all-wheel drive.
• The CTS Coupe is due to arrive this May, and there's still talk of a V version (duh). Apparently GM has a working CTS-V SportWagon on premises and it could arrive as early as next year.
• New Chevrolet Malibu unveiled, but it supposedly won't reach production until 2012.
• All-new midsize Buick model coming within the next 24 months.

We'll keep our eye out as more information becomes available, and if you didn't need a reminder, all of this should be taken with the appropriate amount of NaCl until we get official word from GM. Details about GM's webcast available below the fold.
