If they really had something to hide they would decide not to show it at all. Because I am positive the journalists will rip Sony a new one if it is bad. It's actually better to show it to people who are less critical (ie the general masses) than specifically show it to game journalists with very lofty expectations.
==> i aggry
but, still, Sony need RIGHT NOW a lot of VERY good news
because for the moment Microsoft and Nintendo make advertissement about their games, a lot more than sony does ...
and the best way to do it, it is to show some "video" to EVERYBODY :
internet + game shop.
If it is a private event, and it will be, we will not be able to see anything ..
I'm interesting in the comment of the journalists
but I think that comments AND visual are better (illustrating gameplay and/or graphisms)
Time to Work !
