F-22 finished product capability

hi all, what you lot think of the F-22 and namly its ability of its avionics to actually perform as advertised which is from what i understand the intergratino of data from perhaps 4 or 5 differant sources both on board and off board sensors in the stealthiest LPI manner and to fuse all this data together in real time for the pilot. It seems an amazing idea but does anyone have any idea if this data fusuion actually works or will work,to me this seems a much overlooked side (to us enthusiasts) of the F-22 yet just as critical supercruise and internal weapons and all that. Anyway what you lot think on this?
