I have it.
Translation of GS3 (or AA3) is apparently under discussion right now. One of the factors in deciding to port and translated GS3 will be the sales of PW2, and there's going to be some sort of pre-order incentive to help sales.
Since it'll probably at least take a year to do the translation (like GS2 DS came out a little more than a year after GS1 DS), there could be a chance that GS3 and GS4 (if Capcom decide to translate that) come out at roughly the same time.
