Home run, or as they say in LatAm... "GGGOOAAALLL".

>Something I figure from Ken's words and replies to some members is that we can provide feedback on all that will be considered not only for the deliberables, but also for the release plan, maybe.

Within the scope of things, as I mentioned in my other post here. The release plan is pretty well defined, described in pretty good depth both in the roadmap combined with the June letter and in my posts here. We generally do not say "never", it is not good for our long term plans nor is it good for the community (developers, businesses, vendors, etc). We prefer not to commit to something that may change. But with that said, what we have is a firm outline with specific goals that will not likely change at a high level but will be sculptured over time as to the specifics (implementation details, scenarios, priorities, etc).
