Not much to add to this really, other than linking the video and asking you to watch it (assuming you haven't already come across this one).
I'm not going out on a limb and saying "by golly, he's right!" That would be pointless.
But it's still worth asking yourself if a tenner a month is worth it for what you're getting.
Ultimately, it's up to you. It has no real impact on me playing SW:TOR in the near future, but there's no doubt that Guild Wars 2 could well herald the end of this use of gaming developers as business cash-cows.
For that reason alone, I hope Guild Wars 2 works.
And, yes - I'll be playing it.
