Lol, s'all good dude, Lisa will be in! Keep in mind however that DOAFest is a Japanese event and Lisa isn't really popular with the Japanese crowd so her reveal likely won't be a priority at that event. Kokoro & the new moeblob... err new female character will very likely get revealed and possibly... Eliot, the token bishounen character.
Plus HBA is always running out of stock... they just can't keep up with the demand.
