The PS3 wouldn't bother me so much... I don't own a Sony console, and never have... Although it still wouldn't be very good for Market Growth, just because its not doing as well doesn't mean its any less important to the market... It would also be a great brand name dying out... which is never good...
Microsoft would bother me a little, I've played the 360 many times, and each time its been a blast... I've considered buying one many times, but something always "Came Up". However, I could live without them...
I grew up with Nintendo, like almost all of there franchises, and would be kinda upset if they went... Mainly because of one thing... Nintendo already said that if they went out of the console market, they would give up making software as well... That alone is enough to make anyone want them to live on...
