Possible. PS3 sales my drop like a stone because PS4 is such a good price and people considering PS3 might just decide to go PS4. The same is not so likely with the 360 / Xb one because the price differential between those two is too much.
So I expect 360 sales to drop quite a bit compared to previous holidays, but I expect PS3 sales to drop even more.
But the absolute number of sales of both last gen consoles (as they will be come the holidays) might be too low for 360 to claw back that lead. The other factor in 360's favour is that it's Xb one is releasing in fewer markets,m so there's no internal competition for 360 in many markets. The counter to that is that Xb one is releasing in all of 360's strongest markets. PS4 is releasing in more markets but not in all PS3 markets, so PS3 could have strong sales in those minor markets.
