Sometimes, it's what's not there that clues you in on what's going to happen next. Kinda like how the surf recedes just before a tsunami hits.
Tortured analogy aside, rumors about a PS3 outing for Persona 5 have been circulating the 'Net over the weekend. More fuel was added to the rumors by an announcement for a pachinko machine based on the Shin Megami Tensei series spotted at Japanese website 7Rush.
The announcement in question included a brief mention of Persona 5 towards the end, saying that the game was scheduled to be announced for the Sony PS3. That's what it used to say, anyway, as the part about Persona 5 has since been removed without any explanation. A request from Atlus maybe?
Here are screencaps of the announcement, with the old one on the left and the new Persona 5-less one on the right. The pertinent text is highlighted in pink.
