Metal Gear Solid V: The Phantom Pain was just announced earlier today, and the internet is already buzzing about David Hayter not reprising the role of Big Boss. Well, it seems Kojima has a reason why, but we won't know until later this week.
Geoff Keighley from GameTrailers has mentioned on his Twitter that he will be posting a one-hour interview with Metal Gear series creator Hideo Kojima that includes a confirmation of David Hayter's exclusion from MGSV: TPP and much more later this week. One Twitter user asked Keighly if Kojima-san gave a reason for not having David on board, to which he replied, "Yes".
It looks like fans will get the answer they demand later this week. Until then, keep your eyes posted to PlayStation Universe as we cover all things Metal Gear.
