Fans apparently have been emailing developer Psyonix about the possibility of port for the game, and have been getting a pretty much canned response. "We are excited as you are regarding the release of Nintendo Switch however, we don’t have enough information at this time if it will happen. For the mean time, let’s both keep our fingers crossed that it will," a customer support email from the company said.
This is not the first time that Psyonix has expressed interest in the handheld-cosole hybrid. At E3 last year, Psyonix's Jeremy Dunham said that the company considers all new platforms and the viability of the game on it. When asked if the company would support the Switch (at the time, still called NX), he told Gamingbolt: "Could we do it? Should we do it? And does the community want us to do it? Those are all things we have to consider, and if the answers are positive, then we would."
It definitely appears there is some fan support for the idea, as a change.org petition is ongoing. As Psyonix said, let's keep our fingers crossed that it will happen.
