One of the biggest lingering questions concerns the way the PlayStation Classic will actually be packaged. The box for the system notably revealed that a USB AC Adaptor would be sold separately. Speaking to IGN via email, a PlayStation spokesperson did not comment on the decision to sell power supplies separately, but did note that many widely available power sources could be used."Power for PlayStation Classic can be supplied using any USB power source meeting the 5V/1.0A requirement, including those that come with smartphones," the spokesperson said. So those of us with a handful of iPhone wall chargers lying around may be able to put one of them to good use.This isn't the first time we've seen hardware come without a USB adaptor — notably the New Nintendo 3DS and New 3DS XL did not come bundled with one.The PlayStation Classic comes bundled with two controllers, both not featuring the DualShock or Analog Controller designs. Instead, the controllers are both non-analog stick PlayStation Controllers, which originally debuted with the PlayStation.Asked about whether other controllers, including those like the DualShock 4, could be connected via the USB ports to also function as controllers, the PlayStation spokesperson said "Peripherals for the original PlayStation or later platforms are not supported on PlayStation Classic, which is designed to work with the bundled controllers."That would suggest, barring new controllers made for the system itself, classic titles requiring the dual analog sticks, like Ape Escape, likely may not have a place on the system.While we wait to hear what else will be on the PlayStation Classic, check out IGN's suggestions for 15 games we want to be included on the PlayStation Classic , or find out our picks in the gallery below.For more, find out what Sony had to say about whether more games will come to the PlayStation Classic post launch , and be sure to check out IGN's Joanthon Dornbush and Max Scoville discuss why they're both excited, but also have some reservations, about the PS Classic below.And for more on PlayStation, check out IGN Beyond , our weekly talk show breaking down the biggest PlayStation topics.
