True but not every PC gamer is a laptop user. I'm on desktop, every parts can be swapped out upgrade $150+ (sell old part and get new) every 2-3 years. Laptop GPUs are usually 30-40% slower than desktop. Today the 900M series due to efficiency design, it is close 15-20% from desktop.

Older laptop with 1-3GB RAM with 4 cores or less, those laptop are worth $200-$300 comparing to console $400-500. >.> Console is still much weaker than a budget gaming PC and it cannot be upgraded except the HDD to SSD.

To answer OP
As tech move on, PS3 is limited for ages, PS4 is already at the limit right now too! If you doubt that... seriously go read up more about game development how each company said about X1 and PS4 with resolution gate vs FPS gate. For graphical games, you have a choice to pick 60FPS or 1080p. Some can be both because they are not graphical, indie games. DX12 on X1 might turn the game around but that's just 1 software upgrade that's about it. No more upgrades later.
