A real MiG-35 has yet to be build. Right now, it's nothing more than a marketing designation for a new MiG-29 generation.
The one you've seen at MAKS 2005 and also showed at Farnborough 2006, is the MiG-29OVT, which is nothing more than a demonstrator of the TVC on the RD-33 engines and new flight control system, built from one of the MiG-29M prototypes. The MiG-35 is a proposed version featuring the TVC engines and FCS of the MiG-29OVT, and the improvements of the M and M2 upgrades. It is marketed to the Indian Air Force for the M-MRCA requirement, with high commonality to the Indian Navy MiG-29K/KUB (which is a new MiG-29K development, not the old version). Plans therefore include new RD-33MK engines and Zhuk-ME radar. It really depends on whether the IAF will pick the MiG-35, otherwise the MiG-35 might end up different according to another customer's wishes.
Actually, the TVC engines are optional for the MiG-35. So it might end up as more of a MiG-29M3 eventually with standard RD-33s.
The Zhuk-MAE AESA radar is also being tested and will be integrated on the MiG-29M2 prototype, so that will probably also be an option on future MiG-35.
