Personally I believe Bethesda learned an important lesson from allowing Obsidian to make Fallout New Vegas: Don't allow Obsidian anywhere near them again.
You can also tell by their sharp return to a FO3-"vibe" rather than adopting lessons from FONV such as immersive dialogue, replaced by the stark opposite
It is naive of us to expect a skyrocketing company to care about "old fans", who are dwindling in numbers, growing in age, and becoming more and more irrelevant compared to the hordes of youngsters who loved FO3 as it was, and even resented the "bore-fest" they experienced FONV to be.
My thoughts on the matter anyway. My eager gamer friend has a similar attitude, and it baffles me every time - he seems to believe that movies and games are created as a favor to the consumer, as if Universal Studios sit around, gazing into the sky, sighing, thinking about all the children, the smiles on their faces, wondering what gift to bestow upon them next. Where do people get this idea!? It's money. Only money. Nothing but money. If you give them more money than the other ones, they'll love you more than the other ones.
