How many iPhone Game controllers are out there?

[mthud]

Just wondering if anyone has any idea of the number of iPhone Game controllers that have been sold? I've googled around for an answer but can't find any good source of information on it.

If nobody knows perhaps we can open it up to some speculation

I have been looking for one that would be close to the PlayStation version. Not seen any yet though.

I bought the Steelseries Nimbus from the Apple store over the weekend and like it a lot so far. This site Afterpad shows all the controllers available and all of the games that are MFI compatible. In terms of how many have been sold, but not a ton. Maybe less than 100k around the US. My random guess is so low because I don't think it's marketed that much. There are a lot more games that work with controllers, but there are still plenty of games that are popular that are not compatible. Apple hasn't done any marketing to bring more attention to controllers.
