A truckload of games have interpreters, coming either from indie developers or major publishers. None of these will be able to update their games to the new SDK.

Regarding the interpreters, I used to be right, but it changed at one point. Quoting Henk Boom on the Lua mailing list:

[[ I thought this was already the case. From an excerpt of the agreement on http://en.wikipedia.org/wiki/IPhone_OS#Java

"No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s)."

I've read that the "or" in "downloaded or used" was originally an "and," but that Apple changed it at some point. ]]
