CoolTechZone.com posted an overview on Intel VIIV Technology

At the recently concluded Intel Developer's Forum (IDF), Intel launched its next-generation of digital home platform called VIIV. The name in itself is quite interesting with VI and IV standing for 6 and 4 in Roman numerals, which further translate into 64-bit. VI IV are also mirror images and could perhaps signify dual-core. According to Intel, its latest digital brand is pronounced as "viv" and rhymes with "five" which takes care of showing that this is the next level from the Pentium 4 platform. The naming was either brilliant or a fluke (or both).
