I really doubt there is going to be restrictions on where you can go if their is paid transfers. By the way, don't get your hopes up about world PVP. I have been on a PVP server since release, and the chances of engaging in world PVP is very slim to none. The pub/imp bases and quest way points are too segregated on planets. Only the recent plague event brought to life some faction battles. There really is no difference in PVP and PVE servers at the moment.
