This is a big concern to us over at the SX mini thread. If no further updates are available, then it is what it is. But as I stated in the sx thread, there aren't enough changes to the SX for me to consider purchasing it. Now, if it supposed dual 18650's, that would merit a purchase. Weather it's the old chip or a new one. I'm not a temp control fan. At least in it's current state. I would buy the VF before I would buy an SX mini with the new chipI wonder how Vapor Flask feels about Yihi releasing a newer version of the SX350 J
I seriously doubt any further upgrades will happen for the current version.
