Fallout fans are confident that Fallout 4 is in production, even though the Bethesda has yet to reveal anything on the game. If they are to refer to the latest rumours, then it is unfortunate that Fallout 4 is actually cancelled from production.
The rumours claimed that Fallout original creators, Interplay Entertainment, have been stopping Bethesda from turning Fallout 4 into an MMORPG. The latter is not at all happy because they can’t do as they please with a series that they have acquired full rights to. As such, Bethesda has decided to scrap Fallout 4 entirely.
Of course, the above are based on rumours and they are best taken with a pinch of salt. Fallout 4 is expected to be one of the most profiting video games when released and it is hard to see Bethesda to not produce it.
