Were you asking why nobody has posted in this thread in awhile or the forums? Either way, I dunno. 
I am playing MGS4 right now, though. The graphics...wow...those are going to be hard to top. This is how graphics should be done. Ninja Gaiden could really learn from this. Not everything has to be shiney and look like it's wrapped in plastic to look good. Hair, clothes, skin, everything looks as it should!
The only thing I'm disliking so far is that it doesn't seem quite as stealthy. Like, it doesn't make you feel like you need to be stealthy. I mean, you can still get gunned down if you run out there like a crazy person, but you have so much more firepower now that you don't have to worry about it so much. It's like RE4 in that you went from managing the hell out of your ammo to "I can always get more". Though, you couldn't buy ammo in RE4...anyway. I know you could argue "well, if you want to get some emblems, you have to be stealthy". But, stealth just doesn't seem as necessary or fun. I remember hiding in lockers and doing all kinds of crazy stuff to keep from being seen in MGS2. Now it's like...the lockers are there, but there's nobody to check them. Umm...but I'm only starting Act 2 (of what I guess is out of 5) so I have a bit more to see. Sucks that the last two acts are supposed to be more scenes than gameplay. The cutscenes are fun to watch, but you're not going to watch them on an immediate playthrough or anything, so it's like, kind of yeah. XD
I dunno, it's turning out to be an amazing game. I can't stress enough how great the graphics are, though. These are going to be hard to top. Probably won't happen until FFXIII and FF Versus XIII come out. :P PS3 is really showing what it can do now.
Of course, more and more reasons coming out to be proud to own a 360, too. Several RPGs from Square Enix. And there's a Tales of Vesperia demo you can play if you have a japanese silver account. It's like Tales of Symphonia, only a LOT prettier. I don't care what anybody says about cel-shading or anime sucking, this stuff is sweet. I think some of these people are just insecure and feel making fun of people who like this stuff will make them look cool. Well guess what? SCREW YOU! 
P.S. I think we need to get into talk about some custom smileys or something that looks better. These are just too generic and feel like a step back from the old ones.
