I think they will do something huge for this. I mean, huge like adding goodies as game codes, stickers and so on. I highly doubt it will be a typical Ayu release though. Tales of.. games are way more popular in Japan than Onimusha's ones (I don't really remember if there was some goodies on Startin'/Born to be.. singles) and they're pretty popular among jrpg games as well.
Just wishful thinking tho
because this is her best tie-up she have since years. So would be nice if they will add some goodies.
