Pretty unrealistic expectation then. It's pretty obvious that third parties make games for multiple platforms so them making cross gen titles at the beginning of a new generation shouldn't surprise anyone.
They had Witcher 3 at their 2013 E3 presentation. They've never had to worry about this in the past because they haven't had an exclusive third party event but I would of expected them to go out of their way to show off what some third party devs are cooking and give a glimpse of the systems potential. They went a far more grounded route which is respectable but yeah...
