Buying a console at launch is always a terrible idea, unless you have lots of money you don't want, you have no free time for the 2 good games it has or can make 10 hour games last 100 hours. Sell it, then if you still want to play the PS4 exclusives you can buy it for chips next time they roll out a new console.
A lot of unnecessary hassle and low profit if you know you will just buy back into one at later date.
If it were me and I didn't have to worry needing to sell it then I'd hold onto it and enjoy the exclusives / other cool features of the PS4.
No reason you can't enjoy both. That said though, PC MASTER RACE!!!!!!
. This is where the consoles come in handy, as you can often complete the game and sell it on for the same you paid, then wait for the PC version. Which will be epic if it does come to PC as it'll look amazing with some gfx mods.
