More Weapons?
What you are actually asking for is when the next expansion of GW2 will come out because most likely with an expansion will come new weapons, new skills, new maps, new enemies, new story, new events, etc.
While some of those are likely to also be done before a expansion new weapons seems like something that would be exclusive to an expansion. that being said I hope they do end up putting out a new expansion at some point in time but it seems like people are forgetting at times that the game isn’t even a year old yet.
What I would like to see is a customization in the weapon skills while not maybe as nice as new weapons to choose from it would at least provide some variety choices in how to use that weapon but I guess that’s why they have multiple weapons.
