We all are! Though some of us admittedly more than most. XP

Going by Yoshi-P's Famitsu interview on 2.5, he reiterates that Eureka still remains, and maybe unintentionally hints that this is only the ending "for the time being." I'd like to believe that that beeping, combined with the abrupt nature of the current ending, is a sign that they've decided to go through with Eureka after all, in some form or another. Hopefully as part of Cid's storyline in the expansion, and maybe with Nero returning just in time to return the favor.
