Lonwa,
Well, a lot of questions in a blog post like this one (on future technologies) will go into the territory that we are not ready to explore yet publicly at the time. This blog post is not an exception.
While we are very happy to see a lot of interest, and are dying to answer a lot of those questions (including yours) - the truth is that for various reasons, there is the "right time" to talk about those, but we are not ready to go there quite yet.
Truth is - when time is right, there will be answers to all of those questions and then some. It is a necessary evil in posts that are trying to talk about stuff that is not released yet. But rather than not talking about next version at all, we instead opt for not going into answering a lot of questions that we know that we will get, and are understandable. Rest assured, a lot more information is coming!
