As for the page, yes indeed that was a display bug. No doubt the timing of the exploits make it look official, but I'm telling you, there was, and is, no plan to move out of the open beta phase yet. They are months, not days or weeks, away from it as far as I can tell. Just do the math Chai, 4/30 was day one of open beta, 16 days of open beta would have been ridiculous. Finally, there was no announcement, and there will be a major announcement when beta is over.
The decision to start the engines of their cash shop while still in open beta was specifically my concern, because I knew it would be a real testing open beta. This is the gamble however many f2p developers and execs make. After all the game has been in development for upwards of 5 years, and its time to get paid.
We are in agreement however that closed beta was too short, I would have added a few more months to it. But their argument was a good one, it was time to open the game up to more bodies so they could stress test and polish because much of the core gameplay had been completed a while before then.
