IIRC Stu posted a link about this saw a while ago.
I was looking at the UK DeWalt website and they have 2 cordless versions and a corded one. The rail system is also supposed to accept their router.
I just emailed DeWalt over here and they said that due to OSHA they didn't think it would be available here.
If you're interested in one as a Festool alternative I would suggest pestering them to put it in for approval. I can't imagine it would be that hard for them to get it passed as the Festool model meets the requirements.
