Some good questions, but many of them don't have answers yet. > What will 4.0 look like? Right now there has been no decisions made on a 4.0. It may be just another release, or it may remove some features, but it almost certainly won't be a major backwards compatability-breaking release like 3.0 was. > Which of the know limitations will be addressed? That depends on what the contributors want to put effort into. :) Speeding it up is currently getting a lot of attention. Each new release brings significant performance improvements. > Will it ever be performant on a standalone basis? As stated above, each new release is faster, but it is impossible to predict where it will end up, and even more impossible to know what you consider "performant". For many users, it is already performant :) > Will it ever be native on mobile? That is a question for the owners of the mobile platforms, as they generally decide what languages get first party "native" support on their platforms.
