@vlad321: Cross-region play was probably cut off because long distances always mean big lag, however good servers you have. If you are in USA and are playing against someone who is in europe, you will always have noticeable lag. Even if connections would be perfect, lag would still exists because it physically impossible to get rid of it. I doubt Blizzard would want complaints about lag which is completely unsolvable. The only way to experience lag-free gaming (even in theory) is not to play cross-region.
The only way how to get cross-region without lag is if data could go faster than light. And, right now, it isn't possible.
