During the Killzone 10th anniversary livestream it was mentioned that Guerrilla Games is going to host a panel at PlayStation Experience in Vegas between December 6th and December 7th.

According to what was said, during the panel we're going to learn a lot more about the Killzone franchise and about the studio.

Unfortunately, while it was mentioned that many questions were coming about the new IP, nothing could be said about it during the livestream.

Will Guerrilla Games surprise us with it at PlayStation Experience during the panel or (more probably) during the initial keynote? Only time will tell, but I'd say it's about time.
