I'm also not to sure whether any actual company have thus far come out to support a specific 'software' implementation. I know many are supporting larger blocks but so do most of us.
With that said, I like this idea. We are past the point where bitcoin was just a project to be 'played' and 'toyed' with. There is serious money invested in bitcoin and the developers of core, xt or whatever implementation needs to understand that their actions could have serious consequences.
I'm not saying that the 'developers' are not taking this seriously but it's maybe time that all are given a wakeup call as to how serious this matter truly is.
