there are a lot of good games still released for the PS2.
This is very true. Even now that the PS3 has been out for some time, new games are still in development for the PS2, and not just low quality third party titles either. Developers and Sony both know that the installed userbase for the PS2 is huge, with many people still using them, so it is a market that can still be very profitable.

And this final generation of PS2 games has really been getting as much as it can from the system, with their graphics looking 100 times better than we thought possible at the launch of the system.

I have a feeling that the PS2 could still be seeing some game releases for at least the next couple of years.

I can guarantee that once you start playing God of War you won't want to put it down. The speed of the combat and how quickly you move through the game is greater than most other games and makes the whole experience quite intense and addictive.
