So a while ago in an interview Pete Hines said something along the lines of "we'll see about it" in an interview when questioned on whether Fallout 4 will have the option to turn a voiced protagonist off. I seriously doubt this feature will be present upon release, but it does give me a glimmer of hope that at some point after release this option will be patched in.
The voiced protagonist is my main gripe with this game, the only one I can't actually overlook. The voice itself I could perhaps live with (although from gameplay so far the protgaonist talks way too much, commenting on in-game items and such when not even in conversation) but what I really can't abide is the dialog wheel where we can't see the full dialog of what we're about to say when selecting an option. Ideally I would prefer Bethesda patch in the option to play with a traditional dialog system of theirs, you respond through text options (the full text, not contractions) and the protagonist remains silent the entire game, but I would accept a patch merely adding the full text of the dialog to the options in the wheel instead of the several word contractions.
Basically this is just a plea for information from Bethesda regarding short-term plans for the dialog system in the game. I definitely won't be picking this game up at launch if the dialog system remains as it is, and likely not for quite a few months after unless a patch is released allowing optional alternative dialog systems.
If I just know you have definitive plans to include dialog options like this at some point, I can order the game comfortably, until then I'm afraid I can't. The recent information given on playing on after the end gives me hope (since I was told here you would not reveal information on that before release) you might release infomation on things like this, since it's clearly a really important issue to a lot of your fans.
