Next generation Russian radars.

I am sure that this topic has been done to death here before, but I am looking for information on the next generation of Russian radars. There appear to be 2 of significance,

NIIP Irbis (Snow Leopard)

Phazotron Sokol (Translation?)

These both appear to be intended for the Flanker series, but I was wondering if there were plans to produce fulcrum versions?
Does anybody have any specs, pictures or other information?
