4 SKU's is way too much.

Let's see if they'll alienate the market or make good entry.

I have to hand it to MS. They sure are handling the backwards compatibility nicely. Xbox 360 ran some of the best OG Xbox games. XB1 runs most of the good 360/XB games. XB1X runs those XB/XB360 games at 60 FPS and a higher resolution.

I hope at the very least, Sony has the PS5 able to play any and all PS4 games.

Yeah, I'll just get the Scarlett pro. I want my disc drive and games powered locally for at least one more generation. Let xCloud simmer and jump in when the tech is mature enough that even core gamers would be pressed to tell the difference.

Flops has no correspondence to a console generation.

Next gen consoles, if they use the same Graphics Core Next derived hardware is essentially all the same GPU generation from the PC's perspective.

They would have to.
There are a few components in the Xbox One X which isn't super cheap to produce like the power delivery and the vapor chamber, so a stripped down model would do some big favors from a pricing point of view.

Only a very tiny amount (25~ games in total out of 530~) of backwards compatible games run at a higher resolution on the Xbox One X.

I think I'll go for a cheaper disc-based model initially and migrate that into the spare room when the mid-generation high-end console drops.

Actually, there are about 55 or so enhanced games. You forgot that all the OG xbox games are enhanced too, running at 1920p.

So... 57 games out of 563 titles are enhanced. (OG+360) Not a real significant number either way, certainly not worth jumping onto an Xbox One X for just yet as we have no idea how long this scheme will stick around.

The Xbox 360 at this point is probably the better device to play Original Xbox games anyway, it can play more Original Xbox titles... And those consoles can be picked up super cheaply.

Doesnt the OG xbox BC with 360 have a myriad of technical issues and problems?

Well yeah, those 57 games aren't worth enough themselves, but they are a huge bonus in addition to the current gen enhanced games that are already enhanced.

Though I still hope they add more OG Xbox games (GTA 3, Vice City, Burnout 3, Jet Set Radio Future, etc). 30 games is way too little , especially looking at the fact that we got 500+ 360 titles.

I looked all over and couldn't find a complete list. Care to post one? 

Edit: Nevermind I found it. https://www.xbox.com/en-US/xbox-one/backward-compatibility Pretty underwhelming list. 

4 SKUs?  I'm going to go with alienate it.  This is a similar problem Steam Box faced.  Instead of a nice simple launch, they had multiple SKUs by different manufacturers.  I mean, retailers are going to have to take a stinking course just to know the differences.  Good luck passing that info on to your average consumer.  And then there will be a simple $399 PS5 SKU sitting next to all that confusion.  I think most would just say screw it and grab the PS5.

Also, the OP mentions Navi for the XB2.  I'm thinking they may have to go with Vega.  If AMD is truly working as closely with Sony in creating at least the first round of Navi GPUs as insiders have stated, I just don't see Sony being fine with them handing that tech right over to their competitors.  I would think Sony would have a console exclusivity agreement on that for at least a year or two.
