It's the first step to get there. It was clear that it would be Versus, the delusions of the NBA league some how transferring to NHL just got everyone hyped. If this does well and the NHL continues to invest in to this then 6's could be a possibility in the future, the current iteration of the game just can't support it.
It would support it if they had a fucking announcement stating they would be having a damn esports tournament for 6s. A lot of people who don't give a shit about EASHL anymore would start playing just for that.
