^^+1. Yup you'll have to wait until the region one(US) version is released.
You could also see if your current DVD player can be made to read ALL DVD regions with this link. Just look up your make and model dvd player... and follow the "how too's" to make your dvd player "code free" ie: it will be region zero and play ALL region dvds. That is what I did to my Philips DVD player.
Then just order the Senna DVD thru Amazon.co.uk or Amazon.de(Germany)
