I believe these will be the first 500GB 7200RPM 2.5" HDDs. I've been waiting to get my hands on one for a while now...anyone else? Anyone have any info on when they're coming out (anything more specific than the Q4 08 that they said on the announcement sheet) or possible pricing? And most importantly...will they fit in the MBPs? The 7200.3's fit fine in the MBPs, right?
