Well... I said it loudest :p

Right after the trailer they blatantly said it's one game. They later said the two games together are Metal Gear Solid V, they would change all mentions of GZ to MGSV and then Kojima said on Twitter that GZ is the prologue to MGSV, which is TPP. So far the only mention of them still being the same comes from the head of public relations at Konami, who is certainly not as good a source as Kojima or the other senior members of KojiPro.
