Gaming and games consoles are a huge business, making console and games producers millions every year.
And even though the PlayStation 2, Xbox and GameCube are massively popular, the companies behind them are already working on the next generation of consoles.
Sony will show off their latest console, perhaps called the PS3, at a big electronics show in the US in May 2005.
Nintendo's new machine, at the moment called Revolution, is also expected to be unveiled next year.
No-one knows much about Microsoft's plans for the next Xbox, but they won't want to be left behind so expect news from them too.
But will the PS3 rule the world like the PS2 has, or will one of the other consoles take over?
