The Last Generation?

With the added functionality within the consoles to be devices that are more accustomed to fulfil multiple media needs, rather than just gaming. Plus with the graphics becoming ever more beautiful. Is there a limit to how many generations of console there can be before they merely start are just re-configure the same formula but only with a few minor differences? (A few examples come to mind).

I think this will surely be the way of the future, as everything has its limit. 

Although perhaps the hardware will not be the focus going forward. Perhaps this will be the last generation of consoles that will actually have a physical unit. With services like steam, I believe it may be much more likely that both Microsoft and Sony will release streaming services (perhaps powered by a relatively low priced device, or maybe none at all). Streaming will also mean the bulk of the power is held remotely, negating the need a high-powered console of your own.

It's a sad thought but I think its an inevitable one. The excitement about buying a new console may be a feeling that will soon be no more.
