Wh-what? You guys want beta 3 already?
I'm more than happy with beta 2. It's super smooth and stable for a beta, and eons better than iOS 9.2.1.
I could stay on this beta for a while longer. But yeah, we could see beta 3 next week, not this week.
Beta2 brought with it significant performance regressions compared to beta1 on iPhone 6 plus. So if you own one of those you'd be eagerly awaiting the, hopefully, fixed version.
