I read somewhere of talk of Russian or Chinese made aircraft being looked at? a very brave move if true, I suspect a Western order for 300+ plus units would be a game changer for either country and something both Boeing and Airbus will try to stop through pricing.
recently Michael Cawley mentioned the interest for a 200 seat aircraft (to fully utilise 4 cabin crew).
A couple of days later the new Tupolew 204 (in a modernised version with a couple of tons less) had its first flight - however with no customer for the "new" type the future for Tupolew does not look good.
The introduction of a Russian type as a second fleet into RYR would mean a huge effort - however it could open a new market:
After 9/11 RYR made a bargain in buying discounted 737s when airlines stopped buying - and offered Boeing a lifeline.
Now a deal with Tupolew could safe Tu and give FR the option to enter the Russian market - huge potential for growth included!
