"So far, we've heard next to nothing from AMD about next-generation desktop graphics cards beyond the existing Radeon HD 3000 series. The company made no mention of any next-gen graphics products due this year in roadmap slides at its 2007 Financial Analyst Day last December, prompting some to believe it delayed the products and planned to keep offering only 3000-series cards throughout 2008.
According to German site Hartware.de, that may not be so. The site says it has received a roadmap for so-called Radeon HD 4000-series graphics cards from a reader. This roadmap shows seven upcoming cards, dubbed Radeon HD 4450, Radeon HD 4470, Radeon HD 4650, Radeon HD 4670, Radeon HD 4850, Radeon HD 4870, and Radeon HD 4870 X2, and it suggests they'll be out before long."
