If by RvR you mean Conquest [3 faction PVP in the world], Rift already has that. Soon no gear/power differential PVP either.Just pointing out in case you didn't know and if GW2 doesn't end up as your cup of tea, Rift is bringing in RvR at some point too, might have already put it in.
OT: I am excited to just play a new MMO. GW2 is a fun and well made game.
Slightly between MMOs right now because I choose to not dive into another with GW2 so close. So I am ready for some lite fun until the next raid season starts around November or December.
