Russia armed forces can't seem to stay focus and most likely due to funding problems like any other military. R&D needs steady funding and government support something Russia's arms makers haven't received.

I'll quote some parts
Various maiden flight and supply deadlines were discussed from the very beginning. The T-50 was eventually scheduled to perform its first flight somewhere between 2008 and 2010. In late 2008, the commander of the Russian air force announced that the plane would first take off in August 2009.
What various flights
In the summer of 2008, officials said the T-50 design had been approved and prototype aircraft blueprints sent to the Komsomolsk-on-Amur aircraft-building plant (KNAAPO) in Russia's Far East, where jet fighters will be produced. The plant is currently building three prototype T-50 fighters for future tests, due to last five to six years, while mass production will not get underway before 2015.
This means they have nothing or very little
Although T-50 specifications have not been disclosed, it is known that prototypes and the first production aircraft will be fitted with 117S (upgraded AL-31) turbofan engines from Russian aircraft engine manufacturer Saturn.
Big deal they made this for the Su-35 not any make believe 5th generation platform. What's to disclosed on this I don't get it?
As a result, the T-50 will be a heavy fighter with a takeoff weight of over 30 metric tons and will have the same dimensions as the well-known Sukhoi Su-27 Flanker.
Where the 5th generation design? Nothing but upgraded Flankers Russia can't seem to get past this point. India should invest with UK, France, USA, Sweden, for any 5th generation future project, at least there will be a chance for it to be actually made.
The Tikhomirov Institute of Instrument Design, which had developed the Irbis radar for the Su-35BM Flanker, is now working on the T-50 radar. The new fighter's radar and fire-control system will be designs on the basis of the Su-35BM's systems.
The radar for the Su-35bm isn't finished yet and now the firm working on the T-50s radar? what? Do Russians even believe this?
India is reportedly more interested in the two-seater version, while Russia, with its developed ground and air fight control system, plans to concentrate on the one-seater fighter. There is a possibility that the Indian version of the Russian fighter will be lighter and smaller, and thus cheaper.
Interested in what? one seat or two seats what's the difference it's not even real nor made! I think India would be interested if Russia actually made the stupid thing already.
As of now, one can only make general conclusions on what kind of a machine it will be, based on the known parameters of their technical specifications. The new fighter should be:
- multifunctional - capable of successfully hitting air, ground and water targets alike, including small and moving ones, in any weather or time of the day, against an enemy equipped with high-precision weapons;
F-16 Block-40s been doing this for 10 plus years
- super-maneuverable - capable of performing controlled flight at low velocity and large angle of attack;
Typhoon and other nothing new
The rest of the article we'll I'll stop, I just get a little tired of reading stuff like this and hearing the fanboys in different forums go off on it. Build it, prove, and I'll shut up.
