Rumor has it that Microsoft will be releasing an XBOX One slim in August to be revealed at E3, no other details have been released about this console. The other, more powerful, console is to be released next year. It is rumored to have a 2TB HDD, 4K resolution, 40% smaller than the current console, and a more powerful processor.

According to Polygon, the Xbox One likely due out in late 2017 will be over four times more powerful than the current Xbox One and will likely be announced in the next month, though plans are “somewhat in flux.” Apparently, Microsoft did not have plans to announce the new system in 2016, but is feeling the pressure in response to 4.14 teraflops Sony’s rumored PlayStation 4 upgrade.

The current Xbox One is believed to operate a peak target of 1.32 teraflops, compared to the 1.84 teraflop performance of PlayStation 4. The 2017-due Xbox One is said to have a performance target of 6 teraflops, while the rumored PlayStation 4 upgrade, code-named “Neo,” is said to run at 4.14 teraflops.
