Anyone selling their current systems to buy new systems?

Unless the PS4 has BC, I'm not selling my PS3.

Same thing with my PS2 when I bought my non-BC PS3. Heck. I still have my original PS2.

Never ever do I sell consoles or games.

No, because there's no backwards compatibility. Every couple of years I like to replay great games regardless of their age. I'm playing all the Killzones right now, for instance. When Halo 5 comes out, I may replay all the Halos again. In fact, I even got an HDMI switch last month to create more HDMI inputs on my PC monitor to accommodate the PS3 and Xbox 360 as they transition from the living room to the study. I will keep them around for several years... I plan on using the PS3 for adding a Blu Ray player to my guestroom/study, for instance.
