A mysterious Tweet from Metal Gear mastermind Hideo Kojima today:
"Typhoon 4. It looks like it won't have an effect on the weekend. Thank goodness! However, my health is bad. Prior to TGS, we'll have a big announcement (?) on Saturday or Sunday, so I must recover."
He posted a followup later: "ZOE3 and so forth -- it's not that big an announcement. However, I think you will be happy."
It looks like we'll be hearing some news from Kojima this weekend, assuming his health recovers, but it won't be ZOE3-related.
