Right now we have these images:

But we are allowed one more for hi DPI supported screens. This super old article indicates that banner-1544x500.jpg is also supported and if you look at popular plugins like Jetpack and WooCommerce you'll see their using those sizes. This post and discussion indicate some clarification may be pending though so @cklosowski is seeking guidance directly.
Anyway, it would be nice to have a crisp hi res banner.
@SDavisMedia can you get one of these created with dimensions of:
1544 x 500 and drop it into the brand assets of Dropbox? I'll get this going to see if we can make it happen in a point release.
Coming up with something now.
Been looking at different banners for a while now. Really torn on what we should do. I spent some time getting fancy and actually ended up back at something suuuuper simple, much like bbPress and WP Super Cache. Need to know how y'all feel about that. Take note that the tagline is removed. Cc: @pippinsplugins

More than willing to get more fancy.
I like what you've done here @SDavisMedia. I thought maybe there were a few little improvements which could be made though so, since I know a lot about design, I went ahead and made for you. Here you go:

I don't think I've ever laughed so hard so early in the morning. 馃槀 I love it
YES YES YES! That's it @brashrebel!
LOL I'm taking the thumbs up on my comment as vote yes. Uploading the banner to the Dropbox, @cklosowski.
This is done and pushed to .org
