Nope, the 5es have always been the updated versions... Like the Geforce 3 was the first generation of pixel shaders and it was NV20 and the Geforce 4 was an "upgraded" Geforce 3 and was called NV25. I read somewhere Nvidia was releasing a NV32/33 that was going to be for the inbetweens (probably equivalent to MX, GTS and PRO) but the NV35 is going to be the same sort of jump as the GF3=>GF4.
