Gaming on the move is set to change after two new handheld consoles were unveiled in Los Angeles.
The Nintendo Dual Screen (DS) and the PlayStation Portable (PSP) were both shown for the first time at mega gaming exhibition E3 in the US.
Until now Nintendo's GameBoy Advance has been the big seller, but Sony hope they'll be able to challenge that.
Both the DS and PSP will be in UK shops early in 2005 but Japanese gamers will get them before the end of this year.
