Guild Wars 2

With the things mentioned at the Pax preview I have a couple of questions.

Will the ui be upgraded to include a system similar to the multispec system? Where one can change the gear/traits/skills according to which spec we choose while out of combat?

Will there be an automatic third option purely for underwater combat that activates the moment we splash and start swimming (considering that there are major differences in underwater traits from the land traits)?

build templates are a feature we know ANet has been working on for a while, but that has no deadline to arrive.
