@mattyftm: You may have tried this or it might not work but the same thing happened to me, I lost my save and thought I had to start from the beginning again, but there was a workaround.
Moving over the chapters I could still compare my choices to everyone else, like you usually can after finishing a chapter. Doing this for all the levels seemed to let the game know I had finished those chapters and the choices I made so when I continued it then started from the beginning of the chapter I was playing through when my save was lost rather than from the very start.
Sorry if it doesn't work for you but worth a try maybe
There's youtube videos of Alex Kidd, Shogun and (bizarrely) a football manager who seem to be coming as dlc. Maybe they went for the budget price on release and plan to make money back on a bunch of dlc, which seems like a fine idea.
I'm really enjoying the game so far, a big improvement over the last game which I also enjoyed. I'd be quite happy to drop some more money for some more characters.
I remember being pretty disapointed when Seeds got shut down, though in the end it led to Platinum so it wasn't all bad. Capcom's not been the same since though. Also Game Republic, Cavia and Cing as I felt they all were responsible for some great games and had a good deal more to offer.
