This was the reply I got from Yeti a few weeks agoIs this around the time of the year Yeti updates specs on all of their bikes? Looking to pull the trigger shortly on an SB140 but would wait if it meant getting the 2021 Fox fork/shock.
"Thanks for your interest in Yeti Cycles and the SB130. We generally do out model year changeover in late summer/early fall. We don't discuss new product or any changes until those are publicly released."
