If they started doing more Direct Feeds, and had them update and release more info on specific games/series, that would be nice. I'd watch them.
Like, once a month until their release in October, have a Pokémon X/Y Direct Feed (that's about six videos, could even be 5 or 4, depending upon content) that shows all the new stuff. I'd watch the fuck out of those.
New Mario Game? Toss a new Direct Feed out for it, and follow it up with a couple more as it gets closer to release.
Fuck, do that for all the games. Yeah, you'll have to spend more time making the feeds, but come on, it would show that you have content coming out, everyone gets to see it, and you get constant "wow, that's cool" moments until the game is out. Don't want to flood the viewers with info? Don't make too many Direct Feeds, just a few every so often.
