Would have probably been better if you sticked with Wii U and PC only, my friend. You could have rented a PS4 for the few games you will play on this system.
I for one had a PS3 and PSP (along with Wii, 3DS and X360) last gen but I won't buy another Sony (or Microsoft) gaming system. (Nintendo and PC gaming on the other hand are still a must for me, they deliver the most unique gaming experiences imo.)
I bought the excellent HD music player Sony HAP-S1 instead of even more gaming systems. It costs more than a PS4 and PSV (or even a PS4 and X1) combined. Strange comparison, I know, but for me the 800€ spent on the music player are much more worthwhile than 400€ or less spent on a PS4 could've ever been.
I think there comes a point where you own too many gaming systems...
