Late last month, I reported Planetside 2 was going into beta finally this past Monday, "barring any unforseen circumstances". Clearly, Monday has come and again with no beta in sight, so it appears something did come up after all.
Assuming you can hang in there until this Monday, Sony Online Entertainment president John Smedley is now saying it should be good to go then. Specifically, at 2PM PST.
In the meantime, watch the 15 minute beta walkthrough video below for the 28th time, and see why people are so excited for yet another shooter. And of course, hit the source if you haven't signed up yet.
