Bottom line is that once people are built up in little villages and have some decent gear they will look for PVP as content and I can almost guarentee you that it will not create enough consistent content and people will get bored and start logging off.
This is still likely to be the case even in the full MMO with territory control and sieges.
Here are some reasons why.
1) Resources aren't limited enough to create a NEED to fight over them...and if they were, only the strongest would have them and no one else could make anything.
2) The alignment system actually means something in this game, which is GOOD! except that it further deters random pvp.
3) Full gear loss, again, this is a GOOD THING, however it is another thing that will deter from PVP happening all the time, unless you are always the winner.
All these things will contribute to a world where PVP doesn't happen all the time, and is meaningful when it does happen - WHICH IS FREAKING AWESOME!!! GOOD JOB!!! (seriously, that is great).
...................except....................
Without any PVE (in the form of randomly occuring aggressive mobs), this lack of constant PVP will create a *CONTENT GAP* once everyone is build up in their little towns.
One thing to remember is that PVE does not have to mean static camps, it does not have to mean awesome lootz, and it does not have to mean dungeons or anything lame like that.
It just means that there are things out there that will ACTIVELY seek to attack you and ruin your day....
-------
One thing I would ask is....have any of you played an MMO with no PVE at all?
I want us to seriously think through this objectively, and not just spout the same stuff like "PVP IS GOOWD AND PVE IS STUPID!@"
We're all here for the PVP...some of us just think it needs PVE as well to flush out the game systems and player sustainability.
What do we really see happening, taking all the game's various systems into account, once people are all kinda settled into their little towns.....?
