Epic Games just sent word that they'll be bringing their Unreal Engine 4 to next week's Game Developers Conference in San Francisco. They are taking appointments to show off their new tech to partners and devs as well as potential partners.
I'd bet the few licensees that get in to see this are going to see something juicy as the release says that NDAs are required. This reminds me of a comment made by Epic's Mark Rein at DICE earlier this month. He said that the newest version of their popular engine was running on systems that he couldn't "talk about by name."
Hmmm. I need to find a dev friend and sneak into one of these meetings next week.
