We all know
that Apple announced the release of the first Macs to use Intel chips. To get full speed and compatibility out of
applications that run in Mac OS X on Intel-based Macs, programs need to be recompiled to run natively on the Intel
processors. Apple's coding tools allow for a program to be coded as a "universal" application which means
that the "universal binary" will contain executable code for both architectures in one package, and then will
run the PPC code on the PPC processor or the Intel code on the Intel processor, depending on which is in your Mac.
Blizzard has said in this forum post to expect the universal binary of World of Warcraft for the Mac by the end of January, probably in patch v1.9.3. This is really amazing! Even if this date slips by a few weeks, it won't be too bad since most people won't even get an Intel Mac until February. Go Blizzard, you guys rock!
Now, we just need some specs in a few weeks comparing WoW on a Revision C iMac G5 and WoW on a new Intel iMac.
