I would love to see JetBrains win, I like them as a business, though unfortunately I haven't been using their products in a long time now.
There's so much going on right now, and the push to PaaS is not performing as well in my opinion.
Take a look at how Herdr got viral, and how it exposes protocols that let others come and build with it. Multiplexers are a good bet, though there are plenty of other verticals out there too.
I would say try to chase another ReSharper moment for you guys.
