Surprising pretty much no one, Nintendo announced the SNES Classic today. It will be coming out in September.
One of the big differences between this and the NES Classic is that there will be 9 fewer games for it. While the NES Classic boasted 30 NES games, the SNES Classic is only going to have 21 games total. But in order to twist the knife for classic game collectors, Nintendo announced that the 21st game on the machine is going to be the never-officially-before-released Starfox 2. You can be sure that collectors will be lining up in droves to get the only commercially released copy of Starfox 2.
The SNES Classic is also going to be $80, while the NES Classic was a cheaper $60. Part of this is likely due to the extra controller. While the NES Classic came bundled with one controller, the SNES Classic will have two. Also, the needed hardware to run SNES games is noticeably higher than NES emulation hardware.
About as predictable as the sun rising, but I will likely be trying to secure a pre-order after the debacle that was the NES Classic supply.
