朝から「あのMGS5の画面はどうなんだ?コミコンで発表したらしいじゃないか?」という問い合わせがいっぱい来た。なんだろう?と思い、ネットを覗いたら、その元凶にたどり着いた。でも、あのタイトルロゴは全くのフェイク。期待した方、ごめんなさい。まあ、こういう話題が出ているうちが花かも。
"Queried from the morning "screen that is MGS5? I hear that you presented at the? Comic Con" Hey, that came full. I wonder what? I think, if you look into the net, that came to the ringleader. But, the title logo that is totally fake. How you expect, I'm sorry. Well, the flowers may have come out like this topic."
So as expected, it's fake.. I think? At least that's what I can get out of the Google Translation.
