Would be such an increase of Xbox power really visible to justify buying this new Xbox ?

The visual gap betwen console generations is slowing down despite the fact that the gen 7 lasted 10 years so how can this kind of change really be noticeable to justify buying a more expensive Xbox. I don't see how this can be a success

I also suppose that developers using the same engine for Ps4/XOneV1 games and Xone elite games will probably not help.

So let's suppose that I can find a Xbone for 299 dolars VS a XOne for 499 dollars... I would certainly buy the Xone classic if the graphic gap is small.  

Keep dreaming lol

Consoles shouldn't get more expensive for any reason other than limited edition bundles. Expecting people to pay more for a nor powerful Xbox as opposed to less for an XB1 Slim just isn't very business savvy.

We're more likely to see add-ons and Slim models.

MS is doing exactly what they need to keep doing with the X1. They aren't doing crazy price cuts or anything else like that and just letting it sell as well as it can. They can't win this gen by doing crazy stuff like that. What they can do is release more games for their console that people like and do other things that will continue to raise the interest of gamers. Then next gen maybe people will be willing to switch back to xbox.

I went from xbox to PS4 simply by watching what Sony was doing with the PS3 and what MS was not doing with the 360. Sony was releasing exclusives all the way up and even after the PS4 was released on their PS3. MS pretty much gave up after Alan Wake I think it was. They had some sequels but nothing new. I made note of this and switched when PS4 was released.

They can tempt me if they put a 4k blu-ray player in there, as that is on my to buy list. Those only very recently came out and cost $400, so it would be unlikely. Plus there is nothing in it for MS, they're much more interested in streaming. But sure, if I can have an XBox One built into a 4k blu-ray player for the same price, I'll bite.

My guess for a XBox One Elite is a bigger hdd perhaps even 2tb ssd/hdd hybrid. Yet nothing that would effect games beyond a bit less pop up and better load times from the faster hdd.

More likely is a cheaper version without optical drive, smaller, perhaps even with the power adapter inside. Nice cheap to produce mass market device with keyboard/mouse support running windows 10 UWP. The only box you need when you go to college, windows productivity software will work on it and synch with your windows phone etc.

id buy it if it was slimmer too

Price is more important than power to the average consumer. Sony hasn't been winning this generation in home consoles simply because the PS4 is more powerful than the XBO. They've been winning because their marketing since this generation began has been almost flawless. Releasing a new "Xbox Elite" won't suddenly change that.

I'm gonna play devil's advocate. I would buy a PS4-2 for $400-500 if the specs were there to brute force emulate the ps3, and better run ps vr.

There are xbox people that would do the same (ludicrous speed, snoopy, puggsly, etc are perfect examples on this site alone).

Sony would do that if the market was big enough for that. However I bet they did the math and figured a full redesign with slim Cell build in (cheaper than brute force) will have to be sold at a much higher price than buying a ps3 and ps4 slim separately.
Having separate hardware profiles goes directly against the fixed hardware spec that is the strength of consoles. All that would do is eat into there own profit margins and add a lot of extra work to QA in game development. This is the time in the gen to make money from optimizing the production process and selling the cheaper console to the majority.

This is not the E3 to reveal a minor hardware revision.
