Your logic, yes, i explain you why
Dead Rising 1 wasnt the reason for them to take a 360 : It's mostly because it had big exclusives coming and wasnt the only interesting game, they didnt buy 360 for Dead Rising, but they bought Dead Rising because they wanted a 360 for the games coming, for the same reason, Dead Rising 3 didnt sell good on One.
Microsoft has reported 9 Japanese games in development for the XB1, with Scalebound already announced.
For 360 there were what 4 announced JRPG's with 2 revealed (Blue Dragon and Enchanted Arms).
How exactly were 360 fans buying a console for future titles, and XB1 fans not? ALL that happened was that the Japanese realized that most of the XB exclusives will come over to Playstation (Enchanted Arms, Eternal Sonata, Tales of Vesperia, Star Ocean....eventhing but Infinite Undiscovery and Lost Odyssey).
