I think it would be interesting if the prices would be included in these types of posts. As of this post, Neon is $348 and Gray is $299 which could explain the dip and rise, respectively.

Neon Switch is sold out.

But you have to ask yourself why. Is it because they choose to or is it because Amazon is now refusing to take as many bundles because they were overstocked last year with too many bundles that weren't selling well. Like I said, I'm not saying that's the case, but as an open minded person that is certainly a possibility. 

Switch and Mario are killing it!

Wow the neon switch was out of stock a few hours ago, and now it says it's already in stock again, that was quick.

Has anyone suggested a PS4 price drop yet?

Lol.

Some. It should be at $249.

Sony don't 'react' like that. They have a long term plan and stick to it. There WILL be a price drop for certain but only because it was already planned and once the old stock is exhausted and the new models are installed in retailers across the globe, they'll implement the price drop. This won't be anything to do with 'countering' the success of the Switch, it will simply be part of their long term plan as usual. People who often post 'price cut' in the Amazon thread and simply looking at the fact another console is selling better but Sony look at their projections. If the sales of their console are going to meet that projection they'll keep the price the same. There comes a point when sales stagnate (which is going to be soon) and it's THEN they reinvigorate the market by producing cheaper versions of their consoles. That is the phase we are about to enter. It's planned and won't be a 'reaction'.
