Feb 18 2009 05:39 PM So, I did some research.....
Da Capo i.f. stands for Da Capo Innocent Finale. However, I have no idea if the actual abbreviation of "if" is to imply the "alternative scenario" we're thinking of in the OVA. The title I drew my conclusion from is the PS2 game coming at the end of April, which is WAY after the second OVA is released, meaning that Nemu really may be dead in this scenario since it is not based off the original Da Capo PC game.
On a side note, the limited edition of the PS2 game is coming as a "Kotori Legend Pack," which I assume something nice will come with it. I expect to see that *hopefully* at the next con I go to.
