Microsoft is already way in decline. You think just releasing another 4K capable system is going to change that? As I stated, Sony will still be successful their numbers will be down. Because the jump from PS4 Pro wont be big enough except for hardcore Sony gamers. Even if the systems are 8K capable, 8K TV’s are years off from being mainstream. By 2020 4K will just be hitting mainstream. Its simple economics and technology knowledge doesnt require evidence. Its a projection based on market knowledge.
