1) So much wrong. Sony had about a billion yen in the bank before wii, no debt. Opposite of dying.
2) GBA had sold 80 million units actually making more profit than the PS2 did. Not dying
3) Games dont sell systems? in what universe?
Nintendo sold over 500 million units of wii software by themselves, and you dont think a part of that had to do with install base?
Honestly nothing you said is accurate.
Even if they did who cares
