A couple of points. I think you're all forgetting that if an engine fire bell sounds on T/O, PNF will call 'Engine Fire' WITHOUT reference to which engine it is. The PF will stop the aircraft by closing the thrust levers, deploying speedbarake and using max reverse thrust. He will not necessarily know which engine it is initially, nor does it matter. PNF doesn't call which engine it is because if the fire occurs beyond V1 then the engine is not identified until 400' when PF calls 'confirm the failure' in order to prevent an incorrect diagnosis.
PF should probably look once the RTO is fully initiated as to which engine it is so that he can turn into wind if necessary (although that's a whole new debate).
Also, forget, you're wrong about the effect of the wind. Go to the AAIB accident report and read it, it's incredible what a huge effect 3 kts of cross wind makes on the survivability of the passengers.
