This week's mail sack has been posted on Bungie.net and it answers a TON of questions - as long as all of those questions sound like "Are we there yet?". If you've already watched yesterday's GDC presentation, there's nothing new for you here beyond additional assurance that we'll see Bungie at E3. (If you HAVEN'T watched the GDC presentation, the mail sack provides yet another place to do so.)
