1. PS3 didn't sell due to the price, which was caused by blu-ray, if it was affordable, the majority would have bought the PS3.

2. Next generation, the blu-ray will be much cheaper, making the PS4 more affordable, furthermore, the jump in tech wont really be so much different from what we have now, it wont be a PS2-PS3 size jump.

3. Xbox have two choices, stick with DVD or move to blu-ray, the second is the only way the next Xbox can compete with the PS4.

4. Sony own the rights to blu-ray, if Microsoft want the blu-ray, they're going to be putting money in Sony's pocket, however, the only way Microsoft can avoid this is if we move away from the disc format.

5. Developers prefer Sony, they give developers more freedom and don't tie them down, therefore if the PS4 truely does become the lead console, we can enjoy another Console boom like the PS2 era, with the PS4 having all the games.
