Both Kyoko and Jason made out just fine. Kyoko had a fine second career with John Zimmerman including another top five Olympic finish (including the easily the best combined SP and LP by a US pair since 1984), three more US titles, numerous GP medals, a world bronze medal, fine pro career and most importantly learned to come out of her shell. Jason met the love of his life, also had a fine pro career, and reinvented himself as a premiere coach in the US. Not too shabby as far a pair breakups go.
ETA: along with Meno and Sand (the result of another very messy break up) these are probably the best examples of US pair team splits I can think of in the last two decades.
