Well this is the first year I've watched the E3 conferences. Microsofts was on at 3:30am and Nintendo and Sony's were 2am and 4am respectively!) So here are the impressions of a sleep deprived woman 
Microsoft
Wow this was massively dissapointing! Coming into E3 being a huge 360 fan I was left really disapointed. Hardly anything good to show and down right embarassing with that new camera motion thing and creepy milo program. 
There was some good though.
- The sabotuer- I like the look of this one. Don't usually like shooters per se but I like the theme/setting so pretty exciting.
-1080p and video marketplace coming to Australia
Nintendo
Very pleased with this conference. Although they spend waaay too much time talking about sales and wanting to bring in more casuals (great just what they need to do focus on more casual games 
why not try and keep the audience you already have happy huh?. That vitality sensor thing is just absolutely ridiculous...
Lots of game announcements that im looking forward to though
- NSMB Wii
- Mario Galaxy 2
- Kingdom Hearts
-Golden Sun DS
-Metroid: Other M
-LoZ: Spirit Tracks
Sony
Even though I don't own a PS3 I like how they have remained the most serious out of the 3. Not putting out 100s of casual titles just to make money like Nintendo. 360 is still good for the more hardcore titles aswell but after that motion camera stuff I don't like the look of their future...But sony also showed a new controller and it was just as bad if not worse you just have to see the thing it is uuuugly 
Anyway here is what I enjoyed from the Sony conference
- Uncharted 2- Showed a really nice demo of actual gameplay not just a CGI trailer
-The Last Guardian- This one looks interesting really sweet feeling watching it
-God of War 3- Gameplay looks enjoyable, graphics look like a PS2 game....not very impressive
-Assassins Creed- Not exclusive but MS didn't play a demo so I listed it here. Game looks absolutely incredible
I'm sad they didn't show White Knight Chronicles. Maybe if a few more games start to come out and a slimmer version is released I would like to buy one though as it stands, including the games mentioned above, there are only 8 or 9 games I would even like for it.
They also showed the PSP Go- Very bad design in my opinion not much else to say I just the whole thing pointless...
GRADES
Microsoft- C-
Nintendo- B+
Sony- C+
So what did you guys think. How would you rank them 1 to 3?
