What's happened from the new year up until now really doesn't mean much in terms of the eventual next gen sales outcome. Without knowing the launch and near future line ups, with next to no game play shown, and with Lockhart being an unknown, along with the console prices, everything is still up for grabs.
Assuming the quality and volume of games were all there for both, while a $499 XBSX announcement would create a quake, a follow up $399 PS5 would shift continents. That could be followed up by the biggest aftershock known to gamers in the form of a $299 Lockhart however.
At this point in time, it looks as though next gen just may come down to the wire. Exciting seeing these two go blow for blow. 10 rounds, or 12 ?...
