Retailer postings and insider information.
Fallout 4 was announced via a debut trailer before E3 2015, but no release date was shared. However, there are bits of information that lead me to believe that it will arrive this year. For one, pre-order codes expire October 31st. Second, virtually every online retailer has it marked for 2015. Lastly, a supposed ex-Bethesda employee stated that it's a 2015 title in a significant pre-announcement post
rnWhy It's Exciting:
This new generation of gaming is missing large-scale titles. Dragon Age: Inquisition and The Witcher 3: Wild Hunt have come to the rescue, but this world still needs a new title from Bethesda, the kind of open-world RPGs. Fallout 4 is just what is exactly what is needed.
