The ATI Radeon HD 4850 512MB was to drop to $129, while the Radeon HD 4870 512MB was scheduled to be cut to $149. This was supposed to be accomplished primarily through the use of mail-in rebates, which ATI would help offset. The Radeon HD 4870 512MB was supposed to drop to $149 with a mail-in rebate, but some of ATI's graphics card partners are resisting this as they feel that since the card outperforms the GTX 260, it should compete against that card. They instead are positioning the 1GB version of the 4850 against the 1GB version of the GTS 250 at the $149 price point.
