I dont know how anyone can come to that conclusion when Microsoft/Nintendo are at huge price advantages over Sony. Point being anyone surprised at any sales has yet to see the real numbers start pooring in which traditionally happen at each consoles price cut. Essentailly we're still talking about launch prices in relation to Microsoft as well. Its all about perceived value, and if the cost is too high, sales will be low(er). Sony is in a worse (the worst) position realistically, assumption means nothing.
Draw no conclusions until the price cut battles have started and we get some more holiday sale numbers, right now what Microsoft is doing in comparison to last gen is simply impressive. Land certainly hasnt been claimed.
I guess that is something that has been better for MS this time around, they have been able to keep their launch price much longer this time around and didn't slice it after like a month like they did with the xbox1, so in that sense I guess one can say that they have done better. On the other hand I don't know how much the price will effect initially. No doubt, the cheaper the better, but I am sure initally all PS3 will be sold without a doubt, and lets not forget that the 20GB SKU is the smae price as the PS2 when launched, so for the Europeans that price range is really not as shocking as for the guys across the pond.
How long they will be able to keep selling the PS3 at that price though, especially if MS lowers theirs remains to be seen, but the playstation brand is extremely strong, but sure I don't see many parents bying it for their kids at that price range. Maybe MS does not really care so much about marketshare right now, but rather not lose to much money right now, and compete head to head when the PS3 launches here, by price cuts, and maybe by then they will have gone to lower nm scale and don't loose to much money by price cuts. We will see I guess...
