I saw the title for this news post on the Escapist's Twitter account, flipped out and rushed over. Then I read the article, and I'm absolutely dismayed at the huge leap from "we don't have any plans for a sequel or expansions at this time" to "THE FRANCHISE IS DEAD". Granted, the title is "GW2 may be the end of the franchise", but still seems like a huge leap.
I'm not going to rehash what a friend posters have said above me, I'm not going to point out that this supposed "WoW-killer" quality for GW1 is a complete fabrication, but as far as I can tell, this game is doing okay. People are buying gems for cosmetic stuff, to enhance their bank accounts, or to trade for gold to buy legendary items in the trade post. Our guild even had a couple of recent arrivals with Amazon putting the game on sale. I've no idea if the game is retaining its players, but no matter where I go in the game, even in the wee hours of the night (I play on a North American server, but I'm on GMT+4), there are always players around if I need a hand with a skill challenge.
So yeah, look before you leap. =/
