i give it a 4
the first hour was waaaaaaaaaaay to slow. to much talking and far to many "short glimpses" aka 5 minute trailers of the same shit you've seen 3 times already. but there was also good stuff: killzone obviously and sorcery looked great too and both give hope to the whole motion controller for core gamers thing. and butler was funny ^^.
now the second hour was fantastic. if i had only seen that it would have been a 5.
big disappointment though: no last guardian
