It's gonna be the same deal as last gen with the music games
Is Rock Band 4 supposedly gonna be the only Rock Band this gen?
I just don't see them doing that, they made so much money with the "expansions" last gen.
It will not. Harmonix is coming back with a new attitude(thank you for supporting us, now we'll support our fans).
They're releasing a platform and will support it for the whole console generation.
Activision will most likely publish good music games for $$$ ala Destiny and COD.
Last gen, RB had to compete with GH. It was a battle for marketshare. If either studio put out an expansion/solo artist game, best believe the competition was doing something similar. RB/GH are going in different directions this gen, so we're not going to see what happened last gen. I have faith.
When I heard the devs. of both games talking about their games, it's clear that RB4 will be the dominant party game.
