MGS4 to Have 90 Min Cutscene?!? WTF!?!

I'm sorry, but did we all read that right????  Is this true or did I just blink a little too fast when reading?  I actually had to read this a few times to make sure I was on the right page.  No, it is not that the total length of cutscenes added up is about 90 min.  There is AT LEAST one cutscene (maybe more) that is 90 full min long.

For those of you who watched Cloverfield, it is longer than that entire movie.  So the big question that it raises for me...what the hell takes 90 min to communicate in a game cutscene.  I was not really interested in MGS4 until this morning when I read the news.   Argh...looks like I am going to have to get a PS3 now (it was going to happen at some point).
