does this just mean game will load slightly faster on the slim?

Nope .. it means nothing. Sony hasn't confirmed anything. It is very unlikely that the specs would be changed mid-cycle IF the older generation is unable t also do this.

I do hav eto point out that Sony has done it in the past with PSP-2000 having twice as much memory (used as buffer) to reduce load times on the PSP2000 compared to PSP1000 .... however I will blieve it when Sony confirms it :).

For now Slim is a better value as the only thing missing is Linux install which lets be honest only a very small number of individuals would be interested in.

The things it is better at than previous generation.

- less weight
- less noise
- less power consumption
- Bigger hard drive
- easier HD replacement
