This reminds me of a phrase I've seen, something like correlation is not causation. Just because XSEED happened to skip a couple games that are Vita only, or risque, or whatever else, doesn't mean that's the reason they skipped over them. Unless they say otherwise (and I doubt they can/will), we really can't assume the reasoning behind their business decisions. The good news is other companies are filling in the gaps, so there's no worries. And XSEED is still bringing plenty of interesting games.
