Do you guys think that they'll make a XV sequel the following year it's released, or a "placeholder" so to speak? I've had a theory that BoZ and whatever came before it was only produced so as to make time for a more resourced title, ala DB Xenoverse. This is due to mostly to the questionable quality of titles as of late, and also Treevax always hinting saying "If you want a better title you might have to wait ^^" or something akin; then we've found out development plans for this one have been in the works for at least two years

. If this is the case, and they want the sequel to shine just as much as this one looks like it will, one year might not be enough time. Who knows, at this very moment another title of varying genre could be being developed to fill 2016s(?) place. I'd love it if a quality action adventure or RPG was being developed. That way we'd have quality and variety year in year out, sounds like a good system.
Well if the question is what I would like to see after Xenoverse, taking into consideration it gets a development period of at least 2 years, then I'd like to see a fully open world RPG of the first third of the original DB series. I can't say where I'd like them to start and end at, been awhile (I'm currently rewatching the series), but there could be about 3 in the series (before DBZ). They can go on to DBZ afterwards if they want to, but I think the DB series much better fits the RPG theme, as there is limited flying and more of a sense of adventure. Goku could still use his Nimbus, although when he does it prevents him from training stats and getting stronger, so there is incentive to travel by foot; other than to explore the world! There should also be a pretty good, fun battle system, also making use of Goku's power pole. I can imagine a really great title and series like this, given it's allowed enough time and effort, could be amazing. I'm more a casual gamer, so am unable to say what kind of game I would compare my vision to, but suggestions are welcome.
If the question is what I'd like the see, given a development period of 1 year? Nothing, save us the despair and them the wasted money and talent. I've seen enough.
