I really think it's only possible if you are the market leader to have and support a console over such a long lifetime. Of course developers are still willing to support the PS2, 120 million consoles compared to 50 million current gen consoles, it's a no brainer.
Trying to convince developers not to jump ship for the new Microsoft and Nintendo consoles when PS3 has an installed base of 40 million (random number pulled out of my nether regions, so don't flame me) will not be so easy.
No software support = death.
