Pros

• Metal Gear Solid (Not a huge fan of the series but it's a great snag for 360 gamers everywhere)
• Great showings on the previously known games (ODST, Conviction, Alan Wake)
• New Games announced (Crackdown 2, Forza 3, L4D 2)
• With Facebook, Twitter, and NATAL, 360 is finally putting serious effort to capture the non-gaming populace. A huge improvement over last year.

Cons

• With Sixaxis and the WiiMote, Sony and Nintendo used both Demos and Actual "Traditional" games at their respective showings (Metroid Prime 2 at TGS 05 and WarHawk at E3 06). As for Microsoft, they still needs to prove that this can work wonders in the traditional setting (Painting elephants and Krazy Kickball* are alright, but let's see a "core" game being used.).
• Where's Rare?

Overall a lot is going on the success for NATAL and the games that can come from it. Right now I'm giving the conference an 8.3/10 (I'm very specific!). Solid, but I want to see if all of this potential Microsoft announed today is more than just potential.

*I forgot the name, you know what I'm talking about.

9/10

They could have devoted less time to Beatles Rock Band and had someone from Rare come out and announce a game.

I was also disappointed with Epic's announcement of a XBLA game even though the game looks pretty good.

What now? The Vision camera does not have any games that support motion tech. There are about a dozen EyeToy games.

I would give it a 6.5 out 10, as I am relatively uninterested in Natal. My score will stay regardless of wether or not the new metal gear is an exclusive or not; I think it's impressive that they got it. I really would have liked to see more on games like bioshock and mass effect.

(PSWii owner)  I am not pissed nor am I underwhelmed.  I think the potential is great.  I HOPE for the sake of all gaming that they make great stuff for it.

I give them a 8/10.

• Alan Wake looks awesome.
• Spliter Cell looks really good but it's still not my type of game.
• FFXIII is awesome but not exclusive
• I don't care about MGS
• Natal makes me very optimistic about the future of the human race, that and the man-made sun
• New video services, facebook etc.

• Not my style of game too often
• I think Halo is at risk of being over played.  The reason why the core Mario, Zelda, Forza, GT, GTA, etc keep going is because they only come out with a main game every so often.  While ODST looks slightly more innovative, the animation (or lack of) when you climb a ladder is telling of how the game plays.  Two hands on the rocket launcher and he can still climb. Amazing. plll.  But now I am nitpicking.  The visor is cool but other games have done it.  This isn't fair because I've never been a Halo fan and I like very few FPS.
• Waggle reference.
• Very little exclusive stuff for this year.

Most of the games aren't my style but I think the core-gaming press will give the conference a 9 or a 10 - which is perfectly fair the thing was packed full of announcements and gameplay.

MS did a great job and now I am really excited for E3 this year.

About a 7. They showed some good games, but there were no huge surprises, and what they did show wasn't mindblowingly interesting. A decent show.

Well, lets see here....

New 360 announcements:
Crackdown 2, Halo: Reach, Halo 3: ODST, Left 4 Dead 2, Forza 3, Alan Wake, Splinter Cell: Conviction, Metal Gear Solid: Rising, XBLA games, Facebook and Twitter, 1080p Instant On, Last.FM music, Netflix advancements, Natal, Live Party advancements...

Easily a 10/10!

(ignore all the PS3 owners that are voting .... we can all go and give the Sony presentation a 2/10 when it is done tomorrow)

everything through the MGS announcement was pretty good. yeah sure, we knew about several of them but overall a pretty good list of games and exclusives.

but the ending with facebook, twitter, last.fm, and a camera controller. meh. just didn't have the impact as last years FF XIII announcement and made the end pretty anti-climatic.

7.5-8/10

8/10

- Lost points for ODST.. I was underwhelmed and disappointed.. I kept thinking master chief was going to pop out of somewhere

- Alan Wake looked ok at first.. until he started to pop out flares!!! that was awesome! Wasn't excited till now!

- MGS... mehhh, don't care for the Metal Gear Series, but I'm sure others will be ecstatic

- no Mass Effect 2 announcement could mean loss of exclusivity

- Natal was everything thats been leaked, the guy in the shade needs to learn the basics of looking "cool".. wearing shades in a dark building is not one of them

- Crackdown 2!! Probably my most anticipated game, loved the first one and I can't wait to play the second one

- L4D II, Nice surprise, didn't expect it so soon!

- Halo: Reach, I wish they had more, looks interesting, hoping they have master chief

7.5/10

Lots of good stuff shown, but I reserve the higher grades for the conferences that show me things I was not expecting at all.

Plus that crappy painting they did brought down the score...
