It looks like we're going to be waiting just a little bit longer to see SEGA release Sonic Team Racing, according to their Twitter. The company let fans know that the game would be delayed until May 2019 as they are working to make sure its better than what you expect it to be.
Hey guys! To make Team Sonic Racing the best game it can be, we're giving the team extra time to work on it. Our new release date is May 21, 2019.
We know delays are no fun, but quality matters most. Thanks for your patience – we've got more to show you for TSR very soon!

If you take out all the prep time, the company basically just gave the developers three or four extra months to work on it, but there's no indication of what they're working on. So hopefully, whatever it is will turn out better.
