Yeah, there's an English language patch out, although as far as I can tell there's still a few things which need translation. Does the job though.
After spending a couple of hours playing around in the editor I'm pretty impressed. Visually it's amazing, the environments and units look fantastic. I've yet to try out the campaign, although from what I'm hearing there's lots of issues there. If I'm honest I'd wait until the 505 release in a few weeks time, and see what kind of reaction it gets before you think about buying.
