I ordered one (blue) off of ebay last week. I think it's coming from Hong Kong; don't remember without looking it up on my ebay order details page. My avatar is the one I'm getting.
An English language version of the TamaWalkie has definitely been released in Hong Kong and the Philippines - there are sellers on ebay who live in those two countries that are offering them to online buyers.
It hasn't been released in the USA and (as far as I remember), BanDai has announced that it has NO PLANS to release them in the USA or Europe
