I didn't even realize that Samsung's Galaxy Tab micro-site has been updated:

What's very interesting is that they have a link to the 10.1v (the original Tab 10.1) and it lists the SoC as "1.0GHz tegra20 Dual Core Application Processor", but the new thinner 10.1 SoC as "1.0GHz dual core processor".

Is there a different brain in the beast?!
