Bethesda is brave enough to try out new IP and has had hits and misses. The Evil Within and Dishonored scored well, but Wet, Brink and Rogue Warrior aren’t likely to come back anytime soon. What’s exciting about the publisher is that it’s not afraid to try something new while others stick to a given formula, so I would expect at least one, maybe more, new projects to be revealed.
That’s as good a reason as a Fallout 4 reveal to get hyped for E3 2015.
