No. BC is a big issue for me. I have replaced 2 PS2s. What used to be one of the biggest features of the PS3 to me was it's reliability. The PS2 is hardly a well built machine, but the PS3 is very solid. I don't want to have to keep buying PS2s forever.
I also live in a tiny studio apartment. The reason I only have my Wii and PS2 with me in the first place is it's literally all that fits. The next console I buy is going to have to push out the PS2, and unless that console has either A) The ability to play my PS2 games or B) More good games (impossible) my PS2 isn't going anywhere.
Plus, as Outlawauron said, next Xmas is really a much better time to buy a PS3. They will hopefully have another pricecut and most of the good games will be out. I have a friend who I can leach PS3 playtime off of until then. From now to the end of the year the only games I would buy are Warhawk, Folklore, and Ratchet anyway, and 3 games just isn't enough.
