You can be sure to watch out for the announcement of Spectral Force Legacy for the PSP in the upcoming issue of Dengeki PlayStation and Weekly Famitsu. Idea Factory's SRPG was spotted in a scan in a Japanese magazine, and it appears to be a remake of the very first iteration in the series.
This remake is purportedly set in a fantasy world of Neverland. The scan also shows another SRPG from Ideal, set to come out next month. This title is Blazing Souls Accelate. We'll keep you posted on more details as they roll in.
