I think that WoW's decline will continue and it is a symptom of all these so called "WoW killers" finally whittling down the numbers. WoW won't die and will still be the dominant MMO for a while to come, but the true glory days are over for them. Like it or hate it, WoW has been a force, but I think them losing subscribers is a good thing because the MMO market is finally maturing. What we will end up with is a lot of quality MMOs to choose from that fill different niches. And if the F2P model continues to grow, you'll be able to easily find the one best suited to your tastes and help that developer out by supporting that game.
