Source Engine 2... Maybe?

Browsing the internets and I came across this:

Appears to just be a rumor right now. I'm taking it with a grain of salt. So don't shoot the messenger here. Looks pretty promising though. Thoughts?

looks like valve figured out what shadows are, hopefully you can now use ultra HD textures, that is one thing that bothered me about the newer source games, visible pixels, if it goes with the trend of their previous engine then it should run well, unlike all the "NEYXT GEYN" engines. thanks for sharing man!
