Signs point to yes actually.

I may be a little slow on this one because the article was released yesterday, but over on 1UP.com, they had the chance to interview Ryan Payton, the assistance producer of MGS4.

A quote taken directly from the article...

Speaking in an interview with 1UP a week before the game's release, MGS4 assistant producer Ryan Payton said there is "still a lot of room for filling in the gaps as far as Big Boss is concerned." When asked about the possibility of a Metal Gear Solid 5, Payton responded, "There are some misunderstandings that this is the final Metal Gear game. But it's really the final chapter of the Solid Snake story. That's all."

Most of us knew that MGS4 was not the definitive end of the series, just Snake's story. And with this having been said now, it becomes very apparent (If it wasn't already) that Big Boss is more than likely to be the star of yet another Metal Gear Solid. Although the big question in my mind right now is where/when will MGS5 take place if it does in fact have Big Boss as the lead? We've already had Portable Ops, which filled in a few gaps of the immediate time after MGS3, so will Konami go the route of continuing from there to try and fill the time-line up until the beginning of Metal Gear 1? Will they remake Metal Gear 1 from Big Boss' perspective (Doubtful as a whole game, but would be cool if it was at least a single act or the sort)?

No one obviously knows the answer to any of these questions at this point given that MGS4 was just released in the US 9 days ago. But one can't help but wonder what the next installment will be like...And if it will have Kojima heading it for that matter. But that's a whole 'nother article for a whole 'nother time.

Also, I know this is my second C-Blog based completely on assumptions. Trust me I'm well aware about what they say about making assumptions. I promise for my next C-Blog I'll try really hard to do this again. But I really was never good at keeping promises...
