A friend told me some answers I dont know where but I know  who said them.

1)Sofrno says it will spread to the whole world
See Josh post on the matter

2)I think the **Haemek Davar** says our minds will become more expansive (I guess the eretz is the mind?! then I have to see that one 

   if someone else can find it or any other answers and edit the answer or post the answer themselves before I can Find it would be highly appreciated
