Indeed. Lots of arm-chair analysts in this thread. Taking an XB1 bundle with 4 games and detracting the full retail price of said games to get the value of an XB1 is an... odd way of calculating.
It's not an odd way of calculating anything, just a total of each individual game at the retailer that sold the bundle.
That "full retail price" you speak of has:
Gears 4 at just under £40 - it's only really much cheaper at Smyths and Amazon right now - full retail price at Microsoft Store is £50.
Horizon 3 at just under £40 - can't find it cheaper today in the UK, and again RRP at MS store £50.
Quantum Break at £17.50 - cheapest price in UK, MS store RRP £40.
RotTR at £18.99 - again, cannot find anywhere cheaper. MS Store RRP £50
Taking the real "full retail prices of said games to get the value of the xbox one" would give the price of the console at -£10.00

Aren't these units already sold to retailers? Wouldn't it be the retailers incurring inventory loss on old OG units they bought?
Think there are platform-holder incentives at play here.
MS is selling the old models from £180-£200 themselves also.
Considering how poorly the PS4 was selling before the launch of the Pro, the difference over the Xbox One isn't actually that impressive.
Since the xb1 began taking a monthly sales lead over ps4, it has sold less than 30k more units in total than ps4 prior to the Pro launch. It has been selling fairly similarly to xb1 in the face of some deep discounting, with a little of its own in the shape of those last few OGs for £150/£180 at the end of September.
