It is very likely that Neteller changed banks or at least changed banks for processing their EFTs - and hence the extra day or two.
It could be that the new bank doesn't do these as fast. IT could be that neteller has not built up a relationship with them yet.
In any case, the new law is not what is causing the extra 2 days. Someone is not sitting in an office somewhere watching EFTs and saying seems fishy to me, let's wait 2 days.
