While I have not spotted them myself just yet, some actual photos of the new PALIT JetStream and GameRock graphics cards have surfaced on the web. Below the fold an overview.
These photos come from hwbattle, and show the coolers. I say this specifically as the actual cards used seem to be Pascal (notice the SLI connectors), likely the new RTX PCB was not ready just yet, ergo this quick bypass. However, it does show what the cards are going to look like and that will get you a better impression overall.
Have a peek.
