I see quite a few stores with Guild Wars in stock...
Complain to the manager.
Anyways, about Guild Wars 2, i cant remember much except it possibly coming out sometime this year.
Replacing 1, doubt it. People will more than likely still play GW1. If it reminds me too much of DAoC where a lone spell caster can wipe out an entire group of players, i'll definately be on GW1 more than 2.
As for my comments about it... The startup is a bit slow, but after a while it gets quicker, especially with people to help ya. Main thing I like about it is that the PvP is more balanced than any other game. Theres no BS about someone having better equipment than you in regards to damage modifying stats (Strength, Dexterity, Agility, Intelligence, etc)
PvE really depends on what type of character you play, and what campaign your in.
Prophecies you'll probably find it easy to get a group regardless, since everything isnt necessarily difficult.
Factions people get a bit more selective to who they let in their group. Assassins are a good example
----Assassins have a bad rep in PvE due to a large majority of them charging into a fight and trying to tank like a Warrior. If you want to play one, stay back in the group, let the Warrior tank, and then start attacking.
----Ritualists depending on their setup can be very strong whether in offense or defense, or can be completely useless.
--------Most of their spells depend on one thing or another. Some of their spells are spirits which are immobile.
Nightfall people tend to use Heroes, except for the end-game missions where good players are important.
