Great deal! Seems like PS4 going to take Europe this holidays and XB US. I think Sony does not want to push more in US and instead they want to take hold on Europe market to offset Holidays sales. Even though XB1 may outsell PS4 in US but Europe sales going to offset this. But after holidays XB1 going to suffer with increased price and no exclusives next year half where PS4 still have momentum with exclusives and December event with new game announcements.
Sony are countering MS well seemingly everywhere except the US. Even in the UK where MS is strong, Sony have some great offers out there with most retailers.
This suggests two possibilities to me
1) Sony cannot afford to compete similarly with MS in the US. This can also be read that Sony don't *want* to compete on price because they want to make more money during the holidays.
2) Sony don't have the stock to meet demand if they price aggressively to defend against MS, so there is no point cutting the price. MS clearly have a lot of production available (looking at their need to stop shipments earlier in the year), and Sony have maintained momentum since launch with great numbers. So they simply may not be able to compete on a supply level. If this is the case, I'm sure we'll see pre-emptive November NPD PR about 'sold out everywhere' etc from Sony
