Something Metal Gear Solid-related this way comes
A week ago, Donna Burke, a singer and actress (the voice of the iDROID in MGSV GZ & TPP) well known in the MGS community made an announcement via Twitter:

The short clip doesn't reveal much, and the phrase "Kept you waiting, huh?" was used by all Snakes throughout the series from MGS2 all the way to MGSV. They might announce a new MGS entry, although it's hard to believe they'll make another successful MGS game since Kojima's departure from Konami (we all know how Metal Gear Survive turned out to be) or maybe they'll announce some remasters/remakes of the older games or maybe they'll finally release Metal Gear Solid: The Legacy Collection to PC and the other consoles.
