Threads like this are always interesting and useful in my opinion. Obviously we can't address every wish, much less in the next version, but it's very good to know what people are most interested in seeing.
I can tell you that the next release will be focused primarily on bug fixes. After that the update schedule is less clear for the free, public versons, but registered users will definitely continue to get regular updates with new bug fixes and features.
We may release additional Technology Preview versions in the future with major new features. I definitely think this particular release has been a great success in helping us track down bugs and get a much wider testing pool for sussing out those rarer issues, so it's in our best interest to continue these sorts of releases when practical.
Primarily we are focusing on what will go into the final release of TG2. That is our clear priority, and obviously for good reason. Along the way it's extremely helpful to have some additional testing in certain areas, of course. But ultimately you should look toward the final release later this year to see many of your wishes granted - multithreading, foam, transparency, etc.
