Now or Wait

Could someone please advice me?
I'm now wondering I should encourege Japanese friends to start SL now in English, or to wait for Japanese version. If the user ID or other things can take over into Japanese version, then I can strongly recomend to start NOW. But if it will not able to bring any past obtainings and experience in current SL into Japanese one, then I should tell it to them.

今、始めた方が良いのか。それとも日本語版のリリースまで待った方が良いのか？

When they find that the Japanese version have an edge over the current one, it is just alrgiht that they can register again, isn't it? Basic account is for free.
IMO, there should be little difference between the current one and the Japanese one.

I think its because investments in avatars can add up fast when you start counting multiple skins, hair, clothing shoes and gadgets. Also availability of player-made merchandise....won't be widely available at first.
