It does suck to have to wait for the true ending but I don't see it as a big deal anyway since I always thought the true ending was kinda random. Some person you barely noticed in the game suddenly turn out the be the mega god boss...wtf...? =___='
Beside I never see the true ending as part of the storyline since it feel more like a bonus optional dungeon to grind for loots/money/get 100% demon summon for the game transfer so it make more sense for it to be on DVD
