Sadly, Metal Gear Solid V: The Phantom Pain will not be playable at the Tokyo Game Show 2014. That's the bad news. The good news is that Kojima and Konami will show off a new video during special stage shows while TGS 2014 is going on.

Even better is the fact that a Konami rep posted on NeoGAF that the trailer will not focus on Afghanistan as most of the previously trailers have.
"If it's Afghanistan again..."

"It's not. This will probably be the last thing I can say about it until the 18th. Please be excite."

Let's keep those fingers crossed that Konami will get some public media out for those of us unable to attend TGS 2014 in person.
