Apple will likely never release OS X for PCs legitimately; it would be suicide to do so.
Many companies have tried to do that. NeXT started out as a hardware company, then tried releasing their operating system for PCs. Be started out as a hardware company, then tried releasing their operating system for PCs. Every company that has ever done that, without exception, has gone bust.
The money that Apple makes is in the hardware, not the software. Selling copies of Mac OS X for PCs is as profitable as selling computers, and only a tiny sliver of the peope who have PCs would buy it.
