Sony Japan unveiled its new mid-year PC line-up yesterday. While their Blu-ray Disc-based machines were absent from the list, the company revealed a few details about them.
The Vaio RC300-series machines will include reader/writer Blu-ray Disc drives that support single-layer 25GB discs or double-layer 50GB discs, according to information posted on the U.S. version of its Sony Style Internet shop.

They'll be high performance computers based around an Intel Pentium D dual-core processor and include RAID 0 Serial ATA hard-disk drives, DDR2 (double data rate, second generation) memory and PCI Express x16 graphics. The computers will be based on Microsoft's Windows XP Media Center Edition 2005 and include Sony's Giga Pocket TV recording software, according to the site.
