I can understand the uncertainty in the minds of Mac game companies. But some of the developer comments in the same article were much more positive, and I choose to be optimistic and agree with those!
Re general fears that development of Mac-native apps will diminish: no way. That will INCREASE because of Boot Camp.
Demand for native Mac apps will increase faster than ever now, and demand drives sales. Developers won't turn away now!
The only way demand for native Mac apps would decrease is if the number of Mac users willing to "settle for Windows" increases FASTER than the overall growth of the Mac OS X user base.
Settling for Windows means rebooting, giving up iLife and all your Mac apps, abandoning the security and ease of use of OS X, and--don't forget--PAYING for a copy of Windows. That's too much to settle for unless you have to. And then you'll do it only WHEN you have to. Not by choice. You will still demand OS X and OS X apps.
So I see the number of Mac users willing to settle for Windows being VERY small, increased only slightly by people now choosing Boot Camp Macs for their next "PC." (A great many of them will end up using Mac OS X even if that wasn't their intent at first.)
Meanwhile I see the overall Mac user base growing a LOT--and growing even more because Boot Camp gives switchers a reassuring safety net.
Result: more Mac OS X users, more Mac OS X apps. Not less.
Now, re games specifically: gamers are the most likely to "settle" for Windows because you're not using the OS at that time, and you're not trying to collaborate among multiple apps. Windows is "good enough" at that point, if you accept the inconvenience of having to reboot just to game. Except for three factors:
1. When you go online to game in Windows (or download content, or chat/email to set up a match, or browse for hints/cheats), you are subject to Windows malware.
2. To game in Windows, you must buy--and take the time to install--a copy of Windows. Mac games don't need that. Mac games will run right off the shelf.
3. If you find Windows gaming acceptable (which I can totally understand), then you ALREADY were gaming in Windows. You owned a PC on the side. Mac owners buying Windows games is NOT anything new with boot camp--it was a factor Mac game companies were already contending with. At least now Mac game companies will have an ever-increasing base to sell to.
I trust the game companies to know more about all this than I, but I tend to think the overall growth of the Mac platform will ultimately help Mac game developers more than the harm done by Intel and Boot Camp. The good will outweigh the bad, and we'll all have more games.
I know I for one will gladly wait a few months more for a native Mac port of a game! Will everyone? No. Will everyone buy a copy of Windows because they can't wait? No. All that is needed is enough new Mac users who want Mac games--and I expect that will happen.
