Question On FFXIII-2's Ending(s) *SPOILER ALERT*

Is that "To Be Continued" caption right before the credits explained in any the 9 endings or is it really hinting towards yet another sequel?

It's either hinting at a possible DLC content/ending or an FFXIII-3. The paradox endings are non-cannon endings apparently and don't actually happen.

DLC content has been confirmed btw in the form of character scenarios for lightning, Sazh/Dajh, Snow and maybe other characters.

Also theres the fact that S-E registered the domain for finalfantasyxiii-3.com, which doesn't necessarily mean they're making a FFXIII-3, just makes it more likely. D:
