NeoGAF forum goers are wondering if PLAY magazine has confirmed Dracula X: Rondo of Blood for PSP. In the Letter from the Editor page, Dave Halverson says "Can you say Dracula X meets Symphony of the Night". Later on in PLAY's Most Anticipated games of 2007 page Dave lists Dracula X: Rondo of Blood for PSP as his #3 choice.
Why would Dave put Dracula X as a PSP game if it wasn't coming to the portable? Especially on a list of anticipated games of 2007. That still doesn't explain his comment about Dracula X meets Symphony of the Night. Maybe Symphony of the Night is coming to the PSP as well, or some new game that combines elements of both. Of course the less exciting prospect could be that he was just referring to Symphony of the Night coming to Xbox 360 and Dracula X to PSP.
I suppose we'll just have to wait for an official announcement to find out for sure, but this info is interesting none the less.
