well, this I tell you in only a rumour inside nokia, I work for nokia, at HQ in helsinki/finland and there have been a lot of rumours circulating in the hallways about this. That is Nokia wants to enter consol industry by 2004-2005
Nokia is already making media boxes, see
http://www.nokia.com/multimedia/210t/index.html.The rumour has it that they will do a hand held machine first a la gameboy, but with an integrated mobile phone (of course)
and then later launch a consol.
The possibilites would be hugh with 3G later on, if the hand held could communicate with the consol, the consol could then act as a game server over wireless broadband. Imaging the possibiltes that would bring. To have access to the main consol power on your "gamephone" or what ever it might be called.
this though only what I have heard, and I am not counting on it at all. But atleast you can firm your own oppinion about it
