Gamescom is currently occurring in Cologne Germany with Bethesda showing closed door Fallout 4 footage. Apparently this footage is the same or very similar as the one shown at Quakecon. A couple of site have posted impressions based on what they saw.
Gamespot has a positive impression praising bigger battles with multiple independent sides interacting. There is also a radial menu for quick changing weapons and equipment. They also talk about a battle with Feral Ghouls that sounds like something out of a zombie game.

VG247 has a more neutral impression not seeing that much change from Fallout 3 despite the 7 year release gap.

Also on Twitter Bethesda has announced that you can play after the ending and there is no level cap in fallout 4.
