It's tentative at this point. There is also a rumor that Ron Perelman, majority stakeholder of AM General (creator of the H1...and H2 as a concept) is in the running.
What I haven't heard mentioned yet is whether the Chinese firm (or AM General for that matter) will keep the production jobs in North America, or whether they'll move production back home.
I'm still less than excited about the news, but then I was never in the market to buy a Hummer anyway.
