Weird time for buying console games?

I just can't get rid of this strange feeling when I go out buying games these days. There is so much talk about next generation of consoles that it feels wrong for me to invest in my current system. A quick calculation tells me I spend more than 1000 EUR (1200 dollars) for games just on my PS3 console. There are great games out there like Sleeping dogs and more on the way but I just won't buy them because it feels that next generation is coming out soon. Oh, and there is the new GTA which I think is going to be one of the first next gen games.

What are your thoughts on this? Are you comfortable spending more money for games on current system? Do you think 2013 will bring us the new Playstation and Xbox?
