I play games and I am clueless as to why you think he is clueless.
Apple has, in many ways, entered the gaming market with the iPhone and the iPad. It is not hard to imagine, that with future Apple TV products, enhanced iPads, or with an actual console device Apple could one day end up being in competition with consoles.
I agree that PC Gaming is on a downward trajectory. Shame. Personally, I prefer the interaction of a keyboard/mouse.
Rain is right. I've been pc gaming since the 90's and it's future is not so bright...
I play a lot of counterstrike and call of duty...neither has changed much in 10 years
At least cod black ops will have dedicated servers again.
And as for gaming on a macpro, all it takes is money. Don't have it? Buy a pc.
I am a semi-pro gamer, and you are both equally clueless.
Semi-pro, and pro gamers want a keyboard and mouse (and some us want a good speed-pad) and their input controllers, and never a slow-but-fancy touch screen.
eSports is taking off massively, getting bigger year upon year, and like kids grow up wanting to be like their favourite sports stars, gamers aspire to be like their pro's. I can't see any "pro" tournaments being held on an iPad, like, ever.
Handheld gaming, like console gaming has it's entertainment, and it's place, but it is indirect competition with PC gaming - as the "core" user-base is vastly different.
The iPad is a huge threat to the handheld and interactive console (Nintendo Wii, etc) markets though. Nintendo identified Apple as the biggest threat to their domination of the interactive console/handheld markets recently, while also declaring the war over sony to be won. Nintendo also declared PC gaming as a different ball game, yet again. It is not the same consumer-group that they are aiming their products at.
And, finally, I've noticed 90% of PC gamers who believe it's on the way out are FPS (First Person Shooter) gamers. Maybe, your just bored with a stale genre of games? RTS, RPG and MMO gaming is still rising hugely, year upon year. FPS is kinda static on user levels.
Personally, I got bored of FPS's over 7 years ago, they are all too similar. I buy them, enjoy the single player - but spend very few hours playing them online.
Check out the new Star Wars MMO from Bioware, maybe their is enough shooting in that to wet your appetite, as it's shaping up to be one hell of a good game. A game sure to rake in user levels of well over 1M.
As for the OP original question. I'd love to see one, and I think their is money to be made with the amount of users switching over to Mac's.. However, Apple is Apple - I can't see them openly entering the market with a gaming machine at this time. I think if they were to enter the gaming market, they would only want to in an OS X capacity - and not windows - and they don't have a high enough market share for that.
As of right now, too-many smaller game designers/publishers find no profits (or losses) in modifying/enabling their games for OS X. That would be the limiting factor.
