If they did it will bomb so hard it's not even funny. People who buy consoles don't want to spend $400 on a new console so soon. if they wanted frequent hardware updates they'd game on pc.

Just like they gained nothing with x360, oh wait.

Tracking a little ahead of a machine that peaked late in it's lifecycle doesn't mean much. X1 doesn't even have half of 4 years left before completing it's lifespan. Sales will decrease a lot very soon and it will never recover.

I don't know who you think you quoted but you'd better get your eyes checked.

The console market is very different from other markets : it's quite a small market (compared to TV/smartphone sales), you can only have one model every few years, consoles don't have any compatibility with other brands so you need a rather big market share to be supported and survive. So it's different from a car maker that can happily make profits with 5% shares.  If a car company is little, you can still drive their cars.  If a console maker has 5% shares, you will not get games. That's why there is only place for 3 constructors, and one can die very fast (Atari, Sega, etc.).

I'd say 2019 at the earliest. Doesn't MS profit with the XOne anyway?

I think the next XBox will basically be Microsoft's version of the STEAM box concept, you'll be able to buy various different hardware configs that are Windows boxes.

And yeah I can see it in 2018. The main reason the last gen went on for so long is because Sony and MS needed the extra time to recoup early gen losses (RROD for Microsoft, huge prices cuts for PS3). That didn't happen this gen, so MS is probably eager to reset the generation after 5 years this time. 

I dont think so, that would enrage theyre userbase I think, its too fast ppl who invested on the XOne will feel cheated. 2019-2020 is a more likely release date imo.

To bring out a new XBox  in 2017 would be a slap in the face for all XB1 owners although I do admit that Microsoft has some of the best PR people in the busness.

It is possible that there will be a reveal in 2017 and judging on how well it is received (ie. pre orders) we could see a new XBox arrouf November 2017. If that does not happen then Novemeber 2018  which would be 5 years from the XB1.

One of the major problems with with choosing x86_64 architecture is that it is extreemly easy to change the processor and memory. The only problem would be the motherboard which may need a redesign although from design to layout testing to actual production can be done in a mater of months or even weeks so I am sure that Microsoft is well aware that if they come out early then Sony need only match or surpass (most likely) their specifications and this can be done fairly rapidly.

No. Microsoft knows at this point that is not smart to try and launch two consoles within Sony's developmental decade. It will only make Sony stronger. Besides, they've sold nearly double what Nintendo sold in half the time. No need to stop the money train because people are still buying Xboxes.
