it's funny to see people claiming paternity for suggestions that have been posted multiple times, in multiple areas and by multiple people (especially things that are just a natural evolution of existing systems), but oh, well.

The list of changes is quite fantastic, and some things are happening at an earlier timeframe than I expected, I'm also glad to see that there's no mention of the hate meter, which means we have time to let them know that it's a terrible, completely silly idea and that it should be axed without fail (like jumping, which thankfully has dropped to a low priority, replaced by a much more convenient and less annoying further removal of environmental collision detection).

I would discourage the unrealistically hopeful, though, from thinking that "until summer 2011" means "BEFORE summer 2011". It probably means "before THE END of summer 2011", that given the amount of changes is an entirely reasonable (and actually still quite short) timeframe.
Don't set yourself up for disappointment. If the changes listed come before June the 21st, then great, hats off because I don't even think it's possible (we're a single month away, come on), and that means that they really worked themselves to the bone and beyond. If they all come before september the 21st, well, they still did quite a great job.
