It would be interesting if they did.
However this game is already a success, based upon the ideas of the game. Many Youtubers do gameplays of it and those videos do get lots of views. And there is plenty of hype about this game on YouTube. According to Wikipedia, Frontier has an expected full game release for this game, "Q4/2016".
I still would like to see ALL those rides in Planet Coaster, that was in their official announcement trailer video. I'd also love to see log flume rides and water slides and stuff. Maybe they might add in expansion packs or something. I'd say Alpha 2 is rich with content. A few new rides and terraforming. I like the quality of the games Frontier makes, they also make games for Xbox 360 and Xbox One too, including Screamride and a few others. They incorporate easy to use building tools, so no matter what everyone's skill level is, you can quickly learn how to do stuff without having to take a tutorial.
