Well this is perhaps a bit of a spoiler in a sense. But something interesting happens after the ending of Travis Strikes Again: No More Heroes.
Yeah im deeming it a spoiler of sorts, so only click if you really want to;
It appears that after players complete the game, there will have access to a technical demo which seems to indicate that a new title in the No More Heroes series is in the works. The tech demo shows players how the control scheme for the next game would be like, which is speculated to be No More Heroes 3.
So it is coming?
Keep in mind Suda51 has repeatedly expressed his interest in making No More Heroes 3 in the last few months, and it will happen as long as sales for Travis Strikes Again are good. But nothing has been set in stone just yet.
