I think that was his point...
from the discussion here you'd think the ps4 had no offers at all and the ONE was given away with fries.
Yes, but the difference is MS said this was a promotional sale of the XB1 so people of course jumped on it thinking this would be their only chance to buy it at the low price. Then MS lowered it again after a couple of weeks and talk about a promotional sale again to try to do the same. Sony never officially dropped the price and gave value by adding games. There's a difference between creating 'panic buying' and 'offering value'.
Also, Microsoft said that this was a temporary pricedrop without a defined time span:
"It's a temporary reduction and we're not announcing an end date at this point," Nichols said. "We want to see how people react to it."
So you better get it at that price while you still can...
