The company is currently weighing up whether the PS4 device should be pitched as a key differentiator for the console or a non-essential add-on.Smart to consider it, but I expect / hope it'll be "just an add-on". A key selling point would require massive support from as many games as possible - I mean even if it's built in the system, it'd have to not be shitty by default.
Good that they're keeping it optional to maintain the lower base price.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
