You could make a case for almost all of those that there are other, more pressing circumstances than simply going multiplatform.
For example fighters have tapered off pretty big this gen compared to past gens. The Crash games not only went MP but also changed developers and the quality went way down. MGR is not a MGS game and features a main character many people cannot stand. etc etc
Without knowing the exact cost to make each game, it's hard to say whether they failed or not as a direct result of going MP.
