Even before PlayStation Experience, Sony is racking up third-party exclusives. Early today news of Street Fighter V leaked and Godzilla was confirmed for PlayStation systems during the Game Awards.
Trendy Entertainment is also joining the party, with the news that Dungeon Defenders 2 will be a PlayStation exclusive. The title is coming to PC as well, and arrived on Steam this week as an Early Access title.
