Because people are clever, they bet on the best hardware made by the one with the best support history, you understand what is an investment right ? If nobody invest in it, then nobody will win, games will take much more time to come, you should thank the early buyers, thanks to them, you will have a good library sooner than expected

I'm not so sure about that. Doesn't buying early prove to Sony that it doesn't need to provide great, exclusive games at launch?
