I also don't see where beta testing in the second half off the year translates into 2012 release. Beta should last about a month meaning if it is before November GW2 could be released in 2011.
Specifically, that closed beta testing will take place late in the year. Closed beta testing is unlikely to be a fast process, the fact that's coming so late isn't a good sign and we know for definite that there will be some form of open test. "More activities into 2012" pretty much outright says there won't be a release this year.
I agree with you about the payment models though, people seem to be jumping up and down on conclusions about that. It's a business meeting, they're obviously going to highlight ways they plan on making money from the game more than anything else.. That doesn't mean they're suddenly going to go back on not having a monthly fee (which is the single biggest selling point of the game), nor does it mean they will have game advantage items in the cash shop.
