Is paperback coming back as opposed to paperless eBooks?

My publisher, Tirgearr Publishing, focuses first on eBook sales.  This is true with many traditional publishing houses, Soulmate and Burroughs to name two. There's sound reasoning to back this up. If the eBook doesn’t sell, neither will a print book. That is true, but the readership of romantic suspense is 60% eBook and 40% paperback. In other genres print books took an upswing.  Some readers like both print and e-readers.  My preference is reading on my Kindle.
