1. Nintendo 8.5/10 (9/10 with Keynotes and games on booth)
2. Sony 8/10
3. Microsoft 5/10
The best would have been Nintendo if you speak only of newly announced games from 1st party : Mario, Metroid and few new games.
They also had the best diversity in term of variety of games.
+ Zelda unveilled by Miyamoto.
Second to Sony, who didnt have so much new stuff to show but managed to steal the day with FF14 (i dont care though) and fabulous Trico. Also, the showing of strong games to come GoW3, U. 2 etc. PSP Go was lame
and then MS, who only had a prototype of someting useless by now, Natal. Come back in 3 years with this for Xbox720. Nothing really got my attention.
