On Bundles, bundling is the name of the game, and in the case of Xbox One, unbundling too. They took out the Kinect. So I bought one at launch at $500, and this holiday season you could have the Xbox One S for $250 with a game or two or three, depending on what bundle you got, sometimes with an extra controller. But it was that much cheaper also because it no longer came with the Kinect.
I bought a PS4 at $400 at launch, and this holiday you could get a slim for around $250 with Uncharted 4.
3DS did get a price cut pretty early from $250 to $200 that LockerK mentioned upthread before we knew the price of the Switch.
I was just thinking the Switch will probably come down to the same price as a Xbox One S/PS4 slim this coming holiday. But LMN8R's scenario actually sounds more likely. It will probably still be $300, but bundled with something. Maybe the Pro controller, or with Zelda. Either way, if you want those things, that still counts as a price cut in my eyes.
