Went to my local EB tonight and saw the $34.99 tag. I asked the clerk to scan it and check in the computer (he said they were usually good about re-tagging price-changes immediately), and it rang up as $12.99. He was excited to hear about the price drop, too. (Though seems that this is a 'tween merger YMMV.) He also hooked me up with a Daxter PSP demo.
No cheap Zone of the Enders 2, though. (Other clerk said that it was getting hard to find.)
I've blown hour upon hour playing it tonight, instead of doing the numerous big projects due next week for school. I'm definitely having more fun with this game than Spider-Man 2. Runs flawlessly (as far as I can tell) on my 360; not even any glitchy movies like in many other BC games!
Thanks for the heads up, OP.
