i just came back 3 months now after 4.5 years. guess what, im averaging 5.5 hours aday since then fulltime wvw :) and only goes out to teq, leyline anomaly and tt if i got time, but the rest is wvw. i manage to continue the story but i'm 3 chapters away to finish the lw4. My goal is to have legendary armor, and now i have the tier 2 precursor, and i had the warbringer. So much to do really outside, but i cant have them all. perhaps ill try post hot content when i got bored wvw(which i hope so) like raids, strike mission, icebrood saga, and and im looking forward to unlock the skyscale. going back to your question, i dont think it will be dead. so much end game i cant even keep up with all the end game contents. PS: Don't believe what others will tell you like the negative guy above, play and see it yourself if it suits you. if not, move on.
