It's safe to say that they aren't happy with how things turned out, but they just have to live with this failure. It all won't matter in the end though when FFXV eventually releases to great reviews.
Btw, I don't think it was mainly about recouping when they decided to reboot it. Maybe when it was cross-gen between mid-2011 and mid-2012 as they would have used the same assets as the PS3 version for PS4, just touched up a bit (see the PS3 character models in next-gen environments in the gameplay section from the E3 '13 footage). After after they started development for next-gen only, though, 90% of the PS3 assets had to be scrapped anyway. They couldn't reuse textures, model, geometry, performance capture and not even the battle-system is the same. Some of the 2011 Versus trailer's animations are still in FFXV, however.
It was basically like creating a completely new game from ground-up now, so they could have just used what they had in pre-production for the real FFXV, now probably FFXVI, before 2012. I mean, they had to have something in planning stages at that point three years after FFXIII, right?.
