I thought so as well.
... Or related to July 23 1999. WHAT HAPPENED THAT DAY?
... Well, at the very least, it was a Friday, and:
Mohammed VI of Morocco becomes king.
July 23 to July 25 - Woodstock 99 festival held in New York.
Hijack of ANA Flight 61 in Tokyo.
You're forgetting that it's the (adjusted for time zones) Japanese release date of Persona 2 Innocent Sin, the only Persona game to not get an official English release, hence the "Absolutely no new games releasing today in Japan".
The thing about redoing something is that Innocent Sin recently got a PSP re-release, and this seems to be a hint that this version will be coming out Stateside.
...What? Kotaku already figured this out, that's how I know: http://kotaku.com/5803704/atlus-travels-back-in-time-to-tease-persona-2-innocent-sin
