as opposed to no-one's stage, the more likely scenario
This year, Sega does have a number of things to show so I have some hope for a stage though it's more likely they'll organise it off a pickup truck behind E3 or sth.
Other than P5, there's the Sonic 25th game(s), Total War(hammer), Dawn of War III at the very least. Maybe the new Valkyria and more Yakuza (0, 6) info too.
