These companies just suck, but as long as a retro market that buys everything up exists, they'll continue to do this. How many devices do they have now with the same performance? At least the Arc series has a Sega-friendly 6-button layout. However, they blow it by offering a Sega Saturn color way and performance that can't properly emulate Saturn.
Heck, with that layout they just need to add a single stick and it'd be a perfect N64 device too! But it doesn't have the perform to handle it properly either. How many more interations until this device can handle those two systems? Those are the ones that would benefit from that control layout the most.
