About a month ago this very subject was talked about on the RZR forum. Someone with a connection to a dealer rep had mentioned the phasing out of the current XP 900 platform. There was some speculation that the 900 engine could live on and be used in a revised RZR-S platform. But as it was said here, why have two sport models with similar engine & suspension. I dont know how many have noticed, but the 900 is no longer labeled with the XP, and they are only offering a single color in base & LE models vs all the other RZR models. There is also very little advertizing of the 900 on the Polaris site.
