Of course not, Gaming would always be relevant and there are plently out there that game not on a PS system. In fact PS only make up alittle of the market. Dont forget you have PC gamers, Nintendo gamers, Xbox gamers, Portable gamers, Tablet gamers, Phone gamers, Arcade gamers etc.
To single out PS making gaming what it is today is far from the truth. Nintendo saved gaming back in the Video game crisis of the 80s/90s, ever since then, gaming has never fallen to that level. Infact gaming has grown more on PC then any other platform.
PS contribute but so does Xbox and mark my words this generation both X1 and PS4 will end up on the same level of sales as did the 360 and PS3. If you want to compare sales then Nintendo have sold more consoles in there history including there unstoppable portable devices.
All 4 contribute to each other. Without Xbox and PS going toe to toe with each other then expect another PS3 launch with overly expensive hardware, without PC expect no push for better hardware and without Nintendo there would be no push for quality games and franchises.
