Personally, I find that to be good news. I prefer ES's "just do the thing to get better at it" approach over arbitrary experience points to get better at whatever you decide to upgrade when you level up.
It also doesn't mean there won't be stats. The engine still depends on stats whether or not Bethesda makes UI for it or allows granular control of it. FO4's perks, for example, set various attribute and hidden skill points in the background to hard values because that's how the game handles the extra "power attacks" you can make. Instead of how it was displayed to the user in Oblivion, where you get these extra attacks at 25, 50, 75 and 100 points in a skill, you just upgrade the perk and it sets those values to the necessary milestone.
None of these simplifications stop it from being a good action adventure game. I think at this point if you still consider them to be RPGs first and not straight up action games, you're only setting yourself up for disappointment. They haven't been good RPGs since Oblivion first shifted the series to being more action-oriented.
