lol You're letting the Negative Nancys win by even considering selling it. The sooner you stop letting complete strangers influence your decisions, the sooner you can start living a fulfilling, independent life. ;)

I regret buying at launch as well but with low demand a used console will probably result in a small loss and the system will likely pick up steam in the next year. I'm debating selling if the price spikes before Christmas myself but if I can make any profit I'd probably sell at this point as well.
