I'm an XB first guy. I picked up XB1 near launch, and got into the PS4 universe 3 years later, with the Pro. I have sufficient disposable income to comfortably afford a $500 console. I figure that puts me right in the target market for this system. But, without any exclusives to play on it, and a PS4 Pro available to play multi-plats, I don't see how I'm going to justify the purchase of XBX this year.
Add in the Switch competing for hardware dollars, at $150 less than XBX, and it is hard to see exactly how this system will sell many units in 2017.
