One detailed tipster claims that new PowerMacs will be announced at the upcoming National Association of Broadcasters conference which takes place between April 16-21 in Las Vegas, NV.
The ambitious report claims that the new machines will include the rumored 970MP starting at 2GHz, alongside 2.5GHz and 3.0GHz models. The first Blu-ray drives (Apple adopts Blu-Ray) are expected to make their debut in the top-end model.
Under the hood support for Hypertransport 2.0, PCI-Express, and a new Audio IC is reported. Memory support will be boosted to 32GB of RAM in the high end models with availability of 4GB DDR modules.
While G5 PowerBooks are not expected, a higher resolution "PowerBook HD" is expected to be debuted at NAB as well. The new model is expected to simply boost the resolution of the current 17" PowerBook and offer the ATI Mobility Radeon 9800.
Steve Jobs has made comments at MacWorld SF that 2005 will be the year of High Definition.
