It currently says this on their site with regard to their US customers:
All US members will continue to be able to use their NETELLER e-wallet account to safely transfer funds to and from non-gambling merchants and are not required to close their account or withdraw their funds.
Not sure how this helps, but I would read it as you can still use your account as before, just not to transfer money with online gambling sites. But what do I know, maybe they changed their minds since writing this.
