Theory on the Rising plot

Thanks to the retired Ravi Singh, I saw this teaser for a Metal Gear Rising announcement:

I didn’t bother to comment on it, but before the real announcement is made today, I want to toss out a theory.  April 30th is, of course, the day Jack and Rose met, as we were repeatedly reminded in Metal Gear Solid 2, and the tagline of “Make it right” at the end of the trailer makes me suspect that the plot will revolve around Rose being in danger.  Raiden and Rose reconcile at the end of Metal Gear Solid 4, so perhaps Rose is held hostage, and Raiden needs to fight the PMC’s in order to save her?  Perhaps too, his memory is altered in a test, and he needs to fight and kill in order to unlock his memory of Rose and find her so he can “make it right”?

Wild speculation, but we’ll see.
