It's a video game. I'm definitely not as emotionally invested in the community as you are; I'm not even particularly stoked from Destiny from the stock-standard gameplay videos they've showed us; but Bungie's decision to release the beta early on the PS4 could be any one of a number of reasons; from developer issues with the Xbox, pressure from Activision, to financial incentives from Sony. Truthfully, does any of this even matter? It's a beta and a piddling announcement on the main page; nothing groundbreaking and in truth, a complete non-issue.
