1) You cannot begin a sentence with 'and.'
2) That is standard legal language dealing with any product in pre-release. Clothing companies, music labels, etc will all have a disclaimer saying that about any of their products being handed out to testers pre-release or before major distribution.
3) This is hidden by the lizards living in the moon, but you can see it because you are the chosen one. It is actually a reptile illuminati conspiracy against the PS3 and that was a sentence to cover it all up. You must unite the chosen relics! (etc etc)
