Please treat yourself to a complimentary pinch of salt as there's some info sweeping the streets of Rumorville regarding the naming scheme of Intel's Sandy Bridge processors which are set to enter production later this year and be launched in early 2011.
According to the fresh rumor, Intel's upcoming 32nm chips will keep the Core brand and will still be divided in the i3, i5 and i7 families but the model number will be 'updated' to the 2000 range. For example, there could be a Core i3-2300, a Core i5-2500, and a Core i7-2800. Please note that these names are supposed to be of LGA 1155 parts although the higher-end LGA 13xx+ CPUs should be in-line with them. Expect Intel to be mum on these rumors, at least until Q4.
