There's an interview with Kojima from the GC up at IGN, and pretty much all you need to know is this:

I didn't really expect to see anything of it till next E3, so this is awesome news He also hints at MGS4 being online off the bat, unsurprisingly.
IGN: Speaking of Metal Gear Solid 4, although we haven't seen a lot about it yet, how has the response been?
Hideo Kojima: Well, actually, we showed the trailer to the Konami employees before E3 and it was not very popular, so I was really kind of upset. After E3 and after we showed the US and the world audience, it made me happy because they had high anticipation from that teaser. Also, we revealed the concepts, and the response was good from all over the world.
At Tokyo Game Show, we actually plan to show not only a teaser, but something from PS3.
