I’m sorry to disappoint you, but we are not going to provide any cloud development tools in the near future. The current Studio version is indeed capable of working remotely, but it lacks very important features for real development: intelligent code completion and refactoring. So we have decided to move Studio completely on IntelliJ IDEA, see our 2018 roadmap.
So in the next couple of years we are going to concentrate on making tools that provide the best possible experience and efficiency for real life projects. Perhaps the situation will change over time and we return to this question.
