Retro gaming consoles

I just saw yesterday that the company "Analogue" is making a high end retro NES console (it's been all over the tech websites). This got me thinking, why don't the actual companies of said consoles make retro consoles? Is it cost, demand, etc?

I see nike releasing retro Jordan's every other week and they are raking in the cash from that. The demand for the retro's are higher than the new products.

Why wouldn't nintendo release an OFFICIAL nes, snes, n64 retro system? Or sega with the genesis and master system, etc? Any thoughts

Because most people don't want to pay premium for those older systems and game cartridges when they can emulate them for free or purchase a digital copy for the more noticeable games for a low cost.
