Google wil be VERY carefully watching whats happening between MS, Apple and Linux. It has already started with Android, so its only amatter of software adaptation. Oh and a fifth OS will come out soon: Nokia!
Very unlikely. They will, however, invest in longer lasting batteries and smart energy management processors (as Apple did in the latest Macbook Pro series).
that is a little too soon. But I predict in five years or so, there will be NO physical media and everything will happen over superfast broadband and in the could (thus the end of piracy!).
It's too late in the game, too exotic with its huge CGI Alien worlds, wants to be Sci-fi and love story. Performing well is a matter of definition, of course, does this mean: no bomb at the box office? just a break even, or little better or a huge Darknknight / titanic hit? That I doubt. By the time it comes out, there will have been enough othr 3D movies.
