I also feel this will be the last "generation" of consoles. Though not for the reasons MS seems to be championing.
For me it's that they just don't have a choice and it doesn't make any business sense anymore to hit the reset button every 5-6yrs. And we have the extremely fast mobile computing industry to thank for this.
Once upon a time people wanted to buy things and use those things for years and years. These days people are ok with replacing said things every other year.
So it makes sense for Sony or MS to simply give more powerful hardware every 3-4yrs and try and maintain software compatibility for as long as possible. Eventually the people that own the first iterations of consoles will upgrade and they typically would upgrade to a device that will already support all the stuff they have. So it's just easier all round.
I honestly won't be surprised if at some point we see an option to buy just the console without any peripherals or even a HDD.
