Crash and Spyro were both replaced by two better games in my opinion. Jak and Daxter, and Rachet and Clank. the situation with 3rd parties going multiplaform is getting out of hand and is higly exgerrated.
95% of all sony exclusives will never go multiplaform because sony owns the IP to them. such francises such as God of War, Rachet and Clank, Jak and Daxter, Gran Turismo, and much more. sony owns 22 1st party studios. Thats more than both MS and Nintendo combined.
