Meh. personally, I prefer the older gray, as I have a lot of it in sets I bought on e-Bay, and when you have two different kinds of gray in a city, then..... *wacko*
That said, you have to remember one thing- lego is a company that only care about making money, not losing money, finding more ways to make money and , if the have nothing else to do, stay at the top of their category, so that change is for them and not us.
