Believe this due to a technology in fast growth phase, expect much innovation in coming years. I'd expect more consolidation over the long run as some equipment and/or innovations are proven to be more universally superior.

I see vast majority of streaming equipment as pretty disposable at this point, expect the churning to continue.
