At the same conference in Monaco where AMD has been showing off it's Opteron silicon, VIA has been leaking info on it's next chipsets. They will be incorporating a version with graphics and one without. They will also be using 800Mhz hypertransport connection. You can read about it here at The Inquirer.
Also of further interest in this article I noted some news that VIA will be bumping up the cache of it's 'Nehemiah' core C3 to a healthier 256k.
