I'd love to see more emo / punk. (Not so much pop punk.)
You didn't have just "punk rock" listed, and so much emo these days is mixed with punk (very effectively, I might add), that I'd love to see more of both of those. And when I say "emo", I mean more of what the genre describes in the pre-2000s and post 2000s... there was that time period from 2000 to nearly 2010 where "emo" meant over-produced pop-punk with lots of black makeup and a few screams. That's not what I mean by "emo" though... I mean the more interesting indie-rock stuff coming out of punk/hardcore music but with a bit more interesting/unique song arrangements and more varied vocals (which a lot of people describe as an "emotional" element) - and a whole lot of it is DIY (thus, definitely not over-produced). The "midwest emo" sound these days is sometimes a bit formulaic, but I still much prefer that sound to the early 2000s "emo".
