Until yesterday the PS4 across most retailers has been cheaper than the X1 thats 2.5 weeks out of the 5 of the NPD period before both consoles dropped to $249 the PS4 had a week at $269 followed by a combination of $269/$249 with a $50 free PS plus 1 year card for 4 days.
MS seem to of finally stepped up and are matching or beating the PS4 price at majority of retailers currently with the $229 Miencraft bundle or retailers offering $249 + $30 gift cards.
Amazon and gamestop are still offering PS4 at $249 with a $25 gift card and Walmart and Amazon are also offering the PS4 at $229.
So far the PS4 should be in the lead as it's been the better price or effective price with gift cards but with MS now lowering the pice or offering gift cards with the console should keep them close it could go either way for December.
