There are some amazing Chips being researched by Intel and HP, which work on the atomic level, meaning pathways 2-3 atoms wide, resitors 1-2 atoms. So processing speed, or the capability of what a computer can or can't do will be up to its user, and/or the programs being run on the computer. All we can do is wait.
But a prediction is the move towards "Total Game Emersion", I believe this is a gamers wet dream is to actually BE in a game. So the introduction of systems which provide a feeling of actually being in a Simulated Enviroment, i.e. 360 degree viewing glasses, hand and feet movement interfaces, a Cup Holder, and something to keep the wife entertained while I go battle in the skies over Germany.
-Bids are on-
1- Viewing System (how the "virtual world" is presented to the user)
2- Voice Commands, not just voice com. between users but voice commands to the computer i.e. you say "Move Airfield 64" or "Goto/Join BlckMgk"
