I am excited to see what happens when subs kick in.

I'm not sure you can say Blizzard are a cheap lazy dev, granted graphically the game looks like a turd but underneath it there is a very solid game with very solid dungeon and end game content. (the reason so many people play WoW is because there is so much to do)

There actually isn't, since WOTLK there's about a month of content to do per expansion, then a 2-4 weeks of content per major content update. WOW has the least amount of relevant content of any MMO I've played.

Right now in FF XIV, the only real complaint about endgame is that there isn't enough of it so you have to run the same (generally hailed as well-designed) dungeon over and over. But that changes in 2 months when CT and new dungeons come out.

Lack of good/enough end game content is why every wow-clone MMO has failed since WOW, actually. FF14 doesn't fix this problem at all. Release super quick/easy to level up games with extremely lacking end game content, the bane of every WOW clone MMO's existence for the past decade. 2.1 looks good, but will it be enough? Probably not.

Of course not.
And because it is not enough, SE also plan 2.2, 2.3, 2.4 and so on.
And somedays it have enough content that a new player don't know what to do first.

No, you can't release 2.1 then say "but in 3-4 months you'll get more content!", the 2.1 content updates needs to have enough content to last 3-4 months, if it doesn't, it isn't enough. It might, I hope it does, but I highly doubt it.
