It doesnt really matter where the block size limit increase is implemented(core or xt), it is needed and it will have to be a fork. You cant have a change like that without forking, again it doesnt matter if its in core or xt.
But it seems the developers of core don't want bigger blocks, so it would be called XT as a result. I like the sound of Core better than XT personally.
So I've heard. Higher block limit is a solution for now. In my opinion of course. Which is why I am running xt. If the core devs decide to go with higher block limit then I'll run core again. I agree it would be better to implement it into core. Obviously it cause confusion for some.
