It's not dying down for me, it's more stagnant if anything because lets face it, after DOA5 was announced the main hype came from the next characters reveals.
Of course information about costumes, stages, accessories, etc were cool, but besides the character reveals, Tournaments, the new features in Training Mode, and Online Netcode, everything else was pretty even on my hype meter.
So now that we know what we're getting with our retail build of DOA5, there is no longer reason to hype myself up for that very reason. But once I actually receive my game, then the hype will jump to an all time high because all my mind will be focused on is "TRAINING"...!
