I am a playstation fan, i've owned every singe one including vitas, etc.
But even I would sell this on, purely because it does nothing different than a £300 ps4.
If people are dumb enough to spend up to £3K for different coloured plastic then I would happily take advantage of that.
I am a football fan too and if I ever got tickets to say a champions league final and someone offered me £5K for them (they can sell for this easily a few weeks before the final) I would say yes please.
It's got nothing to do with being a fan it just makes sense to sell it on, it doesn't do anything a normal £300 ps4 can't do.
If you wanted you could sell it, take the £2K profit and spend <£500 of it on getting the best artist in your local area to mod yours to the exact same thing with a bit of paint, etc. You still have a console which looks the same but with an extra £1K+ in your pocket.
