1. I dont think it will be released through CDs, because mincraft doesnt even need 100 mb and on a CD you have space for 700 mb, on DVD for 4,7 gb and on blu-ray up to 50 gb space, so i think the game isnt "big" enough for a release on CD.

2. I'm sure Notch improves the servers ping.

3. It won't be aviable on steam. (at least sometimes in the main screen it says "not on steam")

4. As far as i know it will cost around 20 €.

5. Of course i'll participate in your movie then
