I really dont see that is a big deal if it is the case. I'm a crafter and I almost never sell gear for money. There are tons of other things in the game, usually overlooked, to make for every crafting job even without the gear.

Housing items always sell super well.
Consumables also always sell incredibly well. ( potions, food )
Also don't forget the people leveling, they do need gear as well. ( 1-60 ) don't just think about level 60 i250 gear... Other people want crafted gear as well. I've made a killing selling gear that no one else seems to want to make.
Leveitems as well... are also a nice selling point
I could keep going?

And like Martin said above me, there will more than likely be new glam gear.

To say crafting is dead because there likely wont be a new battle set before the expansion is just silly.
