The wifi removal from PSP was only in the Europe model that was super cheap. 3000 is still default model.
A disc less digital only PS3 is possible. They wouldn't even have to have hard drives larger that what they use now but I would just release a 320 gb version. The PS Store has been getting titles day 1 and with the instant game collection Sony is almost screaming that they are going to do this. The current PS3 model will still be available side by side so people can choose. I don't know what pricing would be but the $200 mark is right there. It would also be best if it was bundled with 3 months or a year of PS Plus so buying the system comes with 12 free games.
As the price of the PS3 drops the need to have backwards compatibility in the PS4 becomes less. Remember when the PS3 slim luanched with a $100 price drop? The PS2 was only $100 so even though people were upset it wasn't packaged in, it didn't cost anything more and the slim had a larger hard drive and used less energy.
Before the PS3 everyone was nice to me :(
