And i believe it took obsidian about a year to make fallout new vegas... If they can make an average game in a year then im pretty sure bethesda can release fallout 4 next year. PLUS, they were working on it alongside skyrim so it can very well be 75% completed so thats plenty of time to finish it and debug it.
