A CodeWeavers blog post has post from around E3 announcing plans to bring DirectX 11 support to their CrossOver software that allows Windows emulation on Linux and OS X computers, which will probably also eventually find its way into the open-source WINE (thanks Linux Today via PC World via Ant). Here's word on the plan where they talk about the games shown off at E3:

How do these games impact Mac and Linux users? Well, they don't. That's the rub in all of this. Most of these games are PC only. However, you might still be able to play these titles on your Mac or Linux computer when they are released later this year using CrossOver. In the coming months, CodeWeavers will have support for DirectX 11; better controller support; and further improvements to overall GPU performance. While these incremental improvements for game support may seem small (at first), the cumulative improvements for game support will allow for many of these games to 'just run' when released. And when more games 'just run' in CrossOver, it won't matter if you're battling against Thor or Apollo using a PC, a Mac, or a Linux computer.
