AFAIK, the P3E upgrade (of which E-Scan and Brimstone are parts) has been committed to and funded by the UK only so far (all the nations having signed up for P2E).
BAE is to fly a test E-Scan radar on IPA5 before the end of the year.
On the subject of the Indian Sukhoi report, given that the IAF said something very similar after supposedly wiping the floor with USAF F-15s in 2003 (I think) - which later proved to be not quite the whole story - are they not in danger of finding themselves being 'uninvited' to such joint events in the future.
