This "they changed the ending because it was leaked" thing has been floating around for a long time, but I've never seen any actual proof to back it up. The "original" ending that was changed was changed when the head writer left, well before any leaks and possibly before much of ME3 was written at all. I've never been able to find a copy of that leaked script (and avoided it at the time), but everything I've heard about it suggests that it was essentially the same as what we got.
