Honestly, I think the only message this kind of position sends is, "this brand has no sales potential" whether that's the intent or not. I don't run out to by games in genres I'm not particularly taken with myself, but I think if people really want "true" DQ games coming over here, they'd do well to loosen up some. By swearing off iOS ports and Heroes and whatever else, you're probably not convincing people to just put regular old DQ out there; you're telling them the brand isn't even worth the trouble. You're drawing a line in the sand they never see.
I don't think old school Resident Evil fans were (too) thrilled that the title that best serves their tastes as of late is a remaster of a decade old game that was already a remake. But Capcom stated that was them trying to see if that kind of game still has it at market and the fanbase bit that bullet. That might pay off.
I don't think it's fair to expect them to just release this stuff. It's not the '90s anymore. If you go all or nothing, corporate suits that aren't invested in the particulars of these things will always pick nothing and move on. If you really think DQ has a future in the west, I think you should be open to compromise.
