You read that right, fans! The Official HasCon web site has been updated with the dates for the next HasCon: September 6-8 2019. That means there will not be a HasCon in 2018. Given the size and complexity of the show (and that 2017 was their first), it makes sense that Hasbro would want to take some time and plan the next convention carefully. Stay tuned for more updates as they come.
Update: Hasbro has sent their official press release regarding the convention.
