1. No, I don't want to play incomplete betas because I've played pleeenty of incomplete betas in the past and see no reason to bother with something that's both going to be an obviously unfinished product and a markedly inferior experience to the actual thing (and considering this is an MMORPG, playing it solo is kind of missing the point).
2. Huh? I don't even know how you went from here to there. Really, I don't.
For the record, you are absolutely wrong. I've played Everquest (and been turned off by its draconian death penalty), played World of Warcraft (and been turned off by its horrendous visuals), and skipped Warhammer Online (thanks to word of mouth AND it aping the visuals of the aforementioned WoW).
3. I really don't know why you're coming to the conclusion that better games are coming out sooner. That is both a matter of opinion and an unsubstantiated claim (especially given that Guild Wars 2 is just recently going into a F&F beta, The Secret World's developer has a really poor track record, and that Tera is effectively going to be dead in the water due to a combination of bad marketing and poor release timing).
That, and Blade & Soul, at this rate, is never going to be standard due to its focus on eastern oriental fantasy and martial arts, of which none of the other big-name MMOs are even approaching.
