Colbert will be great. I've seen him do non-character interviews... There is a good one with DeGrasse Tyson on YouTube, tho it's about an hour long if memory serves. He's still a funny guy out of character, but it was a legit interview.
My only beef with Stubbs (HAHA PUN INTENDED HAHA) is that it's ridiculously expensive. Sweet Baby Rays is the only decent, cheaper alternative that I like.
I don't know how it is on PS4, but on XB1 digital download is the way to go. So bad ass to switch between games, TV, music, whatever...without having to move.
