You're getting your wires crossed, as are a few others.
The hybrid air/coil system is on the Session 9.9, is a Trek development, and available already - but only to those who buy the Trek bike. It's not particularly impressive IMO and the coil feels much better.
The fork with the pressure relief ports and lighter lowers is the new 40 RAD fork which runs a full air spring. It's entirely possible that Trek could choose to run their 'hybrid air' system in this fork if they wanted (because parts are compatible to my knowledge), however that is not how it comes standard.
You're right seems I missed that...
"In a later communication, Mark Fitzsimmons corrected PB's guess that the 40 RAD's spring was a hybrid: "The spring system is unlike anything out there in the gravity suspension world. It is a 100% FOX design that has several different adjustments for individual riders' weight and riding style. It is not a hybrid system. The Trek World Racing team races on FOX designed spring systems."
That is slightly disappointing as I much prefer coils...Maybe I don't want to wait for this new 40.
I've been watching the WC closely, as is it just me or do all the Marzocchi riders need some mid travel adjustment? Spagnolo going over the bars this weekend, Matti eating it Mt Saint Anne, as well as most of the other Mz riders plowing thru their travel in the same section... It just seems they lack Highspeed compression or they simple need to go up a spring. Fox and Rockshox on the other hand look flawless on said parts.
