Nice. It's going to be an interesting battle this year. I think if Sony lowers to just $249, with only a week of $199, Switch will most likely win by a small amount. If they lower to $249, with a few weeks of $199 (and enough stock), then the PS4 will win by a small amount. But, if they actually permanently lower to $199, then PS4 wins easy.
Sony still has some bundling options in their back pocket, too. They still haven't released a standard WWII bundle and considering how much Horizon has sold, bundling the PS4 with Horizon Complete Edition is another viable option. I'm surprised that Sony has not done the former already considering how well COD WWII has been selling.
