Holden based 2010 RWD Chevy SS coming to US?

We keep hearing from several sources that there will indeed be a big rear wheel drive (or right wheel drive as we like to call it) Chevy sedan coming, based on the Australian Holden. Specifically, a high-performance version of General Motors' Zeta platform that underpins the Pontiac G8 will live on as a Chevy SS model, either badged as a Caprice or an Impala. After all, Bob Lutz himself said that the Pontiac G8 platform was "Kinda too good to waste."

The following was spotted on a Pontiac G8 forum:

"My dealer had sent off pictures to GM of the cable portion of the front seats belts rubbing against the plastic on the side of the front seats. In an email sent back to the dealer, GM says that they have no plans to solve what has already been built but going forward a correction is planned. The email continues: ...a fix is planned for MY11.5 Chevy Police Program and MY12 Chevy SS. The fix will involve a protective sleeve that covers the buckle and section of the buckle stem that rubs on the plastic trim."
