I think it is possible that there will be some Gaming computer which will be smaller than a smartphone in the future. Most smartphone has a 5 inch glass touchscreen, battery, speakers, buttons, case, and other features which increase the size and thickness of the device.
Computer parts are getting smallers and faster, and generate less heat. More computers are coming without features like a disc drive, floppy drive, memory card reader, Ethernet ports, etc, so PC are getting smaller. I think eventually there will be more powerful computers which is a size of a small credit card which users plug into a monitor or TV to play games on.
