The PS4 slim has had some great £249 bundles 500GB + BF1+Titanfall 2 was on GAME early in the week for a few days which then got replaced midweek by a 500GB BF1+Battlefront and 500GB Titanfall 2 + Battlefront at £239 each and the Cod bundle has been on sale all week for £219 and for the PS4 slim to only be up by 8% seems rather low to me.
40k first week sales for the Pro isn't good either, It's been building up Pre-Orders for 9 weeks now which would be 4.4k a week but obviously some of that 40k would of been non pre-orders so most likely 3-3.5k a week were from the pre-orders and the general consensus was that the Pro was taking away purchases from the PS4 slim since it's reveal for the past 9 weeks so even if it was taking in the region of 2k a week from the slim sales in the long run the Pro launch has only effectively pushed an extra 20-25k consoles.
This may change over the next few weeks as people may of been hesitant to jump in or feel that paying £349 now isn't the best deal when Black Friday is close by and Sony could just well bundle a free £40 game with it a week or 2 later.
Edit: Tesco already selling PS4 Pro + CoD: IW for £352
