Havn't paid attention lately (raw ns)

So, i havn't been on here in a while. It seems that my last toy (raw ns) is no longer the brightest thing on the block? What's with the CREE XR-E emitter?
I understand it has three stages? .... And is much brighter than the one i currently own with longer run times and less heat? Any beamshots of the old vs. new?
I'm having problems finding any more information than that. I love the Raw NS and is definetly a crowd pleaser but if an upgrade is possible (or a new one as the one i have sees quite a bit of use) then i'm definetly interested. What's the top lumen output of this this new emitter and how long is the runtime with it?
Thanks Guys

The bad news, the XR-E smokes the original. The good news, your NS can be upgraded
