Kojima mentioned how he wanted uncompressed audio (probably what takes up a lot of that 50GB space) for MGS4.

It's good to see that Gamepro were so impressed with the quality of the audio they wrote a whole paragraph about it.

"MGS4 has some of the crispest, clearest sound effects we've ever heard"

Sounds like it payed off.

they don't say anyting about the gameplay in this report

so.. hold your horses still a little..

Though snake is skinned in medieval clothes I think this Gametrailers video shows off the gameplay well (including realtime interactive cut-scenes):

Some dev walkthroughs are pretty interesting as well. If you want you can play the game as a FPS.

This will be the game to define the Seventh Generation of consoles.

This game will be a day one (to around day 10) buy for me.

As a huge MGS fan i couldn't be happier.

First-day buy for me and probably my GOTY (unless FFCC:TCB hits of course).

 It's 3 on easy I believe. But yea, it's crazy if you play it on hard and I feel bad for people who play it on the even harder difficulty. Anyway, Leo-J, shoot their leg and then shoot their head. If you can get in the groove of it, it's not too bad. I believe a chaff grenade will mess with them a little bit as well. 

Looking good anyway!

Never played a MGS game before (other than the demo's) but think i might have to pick this up :D

Sounding absolutely great!
