That's the same way I feel. I have tried not to buy games, but that has not worked out so well. I'm still working on my backlog, but I keep adding new games as well.
I have decided that I will most likely stop buying new games at the end of this generation. This was actually the first generation of systems I bought systems while they were still in their prime as I usually waited until they were nearly done. I have a lot of games to get caught up on, so depending on the next gen systems and/or if they go download only, I think I may hold off for a while.
But, for now, I'm going to keep buying stuff that I don't really need... First up, the DSi Xl, followed by the 3DS
I have a ton of DS games and have gotten a ton of use out of the system so it was in no way a bad purchase for me but with the way Nintendo is releasing system after system I think it would be best for me to wait until at least the 2nd revision of the 3DS to get another one. I have a lite and I skipped over the whole DSi Generation.
About consoles I don't need I just bought a PS2 (a working one for a very very low price) and I am about to blow $300 on the newest iPod touch (though at least half of this is being paid for with giftcards). Not to mention all the PS2 games I am about to blow money on, although they are all $10 or less per game. I haven't bought any portable electronics since 2007 though and I don't have a cell phone and I did skip over the DSi generation so the iPod is kind of justified, at least I can justify it that way, haha.
For the PS2 its the first PS2 I owned, never owned it before. I feel kind of silly walking into gamestop and buying $2 eyetoy games (and other cheap games) but meh, cheap fun is cheap fun.
I just don't see the point in buying a DSi, it has nothing that would add to the experience of playing games for me, and DSi ware is nothing I am interested in especially since its game are crappy, expensive and locked to one console and you can't get them back if you lose your console or upgrade. It also doesn't have a GBA slot which I need since I am a huge fan of the Pokemon RPG games.
I really don't need to buy anymore modern consoles, since I am truly overloaded with games.
