JSF-Ski

Looks like Russia will start developing a fifth generation fighter with Indian financial backing soon. Does anyone have any idea what this plane will be like? Is it supposed to match the JSF or will it be more a competitor to the Raptor.Who do you think will develope it- Sukhoi- Mig or both with the help of Yak.What will be its characteristics. Will it be based on the MIG-MFI or the Sukhoi Berkaut or a completely new design.
