Even if they do relocate the EU servers, how many people are actually going to move? I didn't even realise when I started playing that there was a so-called EU server cluster (which is entirely pointless if it's still located in the US) and I just rolled on a server a bunch of other people played on, and I'm unlikely to move now. Based on past MMO experiences, dedicated EU servers tend to be barren lifeless places filled only with people arguing in public chat about which language everyone should be speaking in.
