> Why is Internet Explorer leading with HTTP/2 implementation?

Leading? Firefox and Chrome already support HTTP/2 already (and SPDY, the basis for HTTP/2, for a long time now), just not enabled by default.

You are right and given that its a tech preview, this is Microsoft catching up.

Their real problem of course is IIS. We'll probably have to wait for IIS9 which I cannot see happening for another two years. IIS8.5 appeared 12 months ago in Windows Server 2012 R2.
