I'm not sure what the big deal is about this.
I think alot of people are scared that raising the limit to 8 billion is going to negatively impact the value of what they'll own - when they should though this will go unchanged, it'll simply just scale.
I'm in NEM for long term, so whether it changes to 8 billion or keeps it at 4 is of no concern to me - i see pro's and cons to both decisions and really i think either one isn't going to hurt.
My opinion is that changes this big this late in the game are a very bad idea.
