Intel's following suit on SiS's announcement for their DDR3 supporting chips & chipsets. Like SiS, Intel is aiming for a launch of their Bearlake chips by Q3 '07. Oh DDR2, we hardly knew ye...

"There’s no mention as to why the DDR3 touting Bearlake-X and Bearlake-G+ will arrive a quarter after the DDR2 supporting Bearlake-G and Bearlake-P variants, though it could be possible that Intel wants greater channel availability of DDR3."
