User blog comment:Commdor/BioWare Reveals ME2 PS3 Content Details/@comment-2088100-20101107002231

this post on the BioWare forums (As pointed out on the ME2 talk page by DetailedSubset) should put to bed any doom-saying about the "new mission." As it turns out, there was an error in translation. The "6 hour mission" is in fact referring to on-disc content (Kasumi, Overlord, LotSB, the Catch-up comic)" and not some mission that's made exclusively for the PS3. BW producer Jesse Houston later posted that their goal is to "create parity not disparity between the three versions [of the game]". So that last bullet-point is in fact just a restatement of already-included "extra" content.
