"But we are looking at GT5 across all platforms, just to see what makes the most sense."
It sounds to me like he meant to say something like "from all angles." Possibly meaning that while they usually give Polyphony free reign to do what they want, Sony needs this game out ASAP, both for revenue and system selling reasons.
Honestly, the notion that they are looking at versions of the game for all platforms doesn't make much sense in the context of the sentence.
