If you don't have a pure Linux port in the plans, then hopefully you could help make it working with WINE so more people can use it.
But preferably please create a native Linux version. Not only with an Unreal plugin, but also Houdini, Unity and maybe the others as well (with the exception of 3ds Max, everything else run fine with native Linux releases).
There are many people that would switch to Linux immediately if more programs added support (now it's basically only Adobe products that hold them back, though that might have changed the last couple of weeks).
