Blu-Ray has yet to bring a profit to Sony and won't for a very long time, even then there is no garantee it will become the dominant format over DVD before the next step in formats emerges. Eitherway, Blu-Ray isn't part of the gaming market, its just you trying to cherry pick anything Sony related to try and offset their loss in the gaming market.
Unless you're willing to argue the gaming market was worth sacrificing for Blu-Ray, then your argument has no bearing as Blu-Ray being a gain.
Sony's gaming division has lost ground and revenue that it will never gain it back this generation alone. Both Ninty and MS are expanding and growing in this market, no matter what happens, both will be at a gain. No matter what happens, Sony will be at a loss.
1: Stop making shooters. Please. You're not Valve or Free Radical.
2: Stop trying to force photo-realism down my throat until you can get out of the uncanny valley. Work on style and presentation instead of just pixels and bloom.
3: Try something weird and new, and hope we like it.
You'll cut costs way more than you cut revenue, and thus increase profit.
