I don't see it being significantly more powerfull than the PS4 but I could be on par or slightly more powerfull.
Nintendo can cut costs in other ways. Could have a model with a 500gb hard drive but no disk drive and then a model with 64gb harddrive but comes with a disk drive.
If it launch late in 2016 with no disk drive or disk drive with lower sized hard drive it could by priced pretty low at that time.
