Unconfirmed: BioShock 2 for Xbox 360, PS3?

Shacknews offers some can-only-happen-on-the-internet type speculation on what platforms BioShock 2 might hit.
While all five roles--senior designer, lead designer, character rigger/animator, senior animator, and FX artist--generically list PlayStation 3, Xbox and Wii under platforms, nothing else within the job descriptions implies a Wii edition is underway.

However, the text for the role of senior designer specifically notes that PlayStation 3 experience is required, strongly suggesting that a PlayStation 3 version of BioShock 2 is being developed alongside the possible PC and Xbox 360 editions.

Additionally, the job listing for character rigger/animator reveals that the game will take place within the fictional underwater city of Rapture.
