Toshiba's 1.8" HDDs

[ArkiStan]

Does anybody know if Toshiba's 1.8" HDDs (the ones they use in the iPod) have broken the 160GB barrier? I know they plan to mass-produce the 240GB version in 2009. I'm just trying to get a sense of what the HDD capacity will be for the next iPod classic, which could be released pretty soon according to past model release cycles:
