everybody always gets to involed in these competition things. All a company cares about is that they can make a profit. Wile Xbox 360 and Ps3 is very competitive towards each other constantly selling consoles at a loss, they still make money off their games. DS and PSP isn't near as competitive as they both make profits. The only thing that will make them not make another PSP is piracy, because that is where they lose money. Unless a console or handheld wont sale at all, they are not going to quit because they are making a profit. PSP has proved to do well with ove 50 mil being sold. DS is far superior in games and sales but doesnt mean sony is dropping out. Btw don't say apple and nintendo are being competitive. Apple makes mini games, not games. And they are not gaming platforms, just something that can play games as an accessory. Imo, nintendo will always win in handhelds due to their games fit better on handhelds, but its not gna stop other companies from making handhelds.
