I don’ think GW2 is in a position to improve, it’s way too late.
And I don’t think they canceled whatever big project they have. Only “setbacks”. But the way they handled GW2 makes me doubt of any future title. I think GW2 still runs on a DirectX 9 client while they were promising even DX12. They simply let it “exist” with that weak living story excuse but no serious work was put into it.
GW2 won’t shut down because it’s their only source of income, but they are forced to deliver something else now.
