Is it a bad time to upgrade to an OLED?

I currently have the LCD model but was thinking about buying a 512gb OLED off Facebook for $440. I figured I could sell my LCD model for about ~$300 so net it would only cost me $140. With CES coming up next week, with the potential for more SteamOS portables and the switch 2 announced, would you wait another week to see what’s coming?
