Hardmac claims that according to their sources, Mac OS 10.5.2 and new Mac Pros will be released at Macworld 2008. Among the claims:
- Apple is actively working on Leopard to benefit as much as possible from the recently released Intel Mac OS X compiler and libraries, including SSE4 support. Mac OS X 10.5.2 should be released for the keynote and fully takes advantages of the last Intel compiler and libraries. According to our sources, it should be the largest and most important intermediate system update ever released by Apple.
- the new Mac Pro will be immediately available after the Keynote, and the hardware specifications should be as follow:
* 8 Core Xeon Penryn for all (3.2GHz for the high-end model)
* new graphic cards should be available, among them the latest Quadro FX from NVidia
* Apple should offer Blu-ray burner as BTO
Mac OS X 10.5.2 may very well come, as Apple often has to update the OS to support new hardware. Even if a new Mac Pro does not arrive, other more reliable rumors have pointed to an "ultra-portable" laptop being introduced at Macworld.
However, other aspects of the story lead to some doubt. Apple has typically not used Macworld to discuss its professional workstation or server line. In addition, claims that Apple will use Itanium 2 processors for an upcoming "Xserve Ultra" appears to be farfetched and remains uncorroborated from traditionally reliable rumor sources.
