If you mean "Peter Todd has convinced some big mining pool operators not to increase the size of the blocks they create" -- then great! That's the free market at work, big mining pools should be free to create blocks that are as large or as small as they like, and to accept or reject other's blocks for whatever reason they like.
This + 1000. It would be wonderful if developers raised the hard cap and miners at least initially didn't make larger blocks. The cap should only be a security mechanism. I disagree that no cap is necessary but the cap should be high enough that the economic decisions of rational miners are setting a "defacto" cap lower than the hard security limit cap.
