Will roster sharing be cross-platform?

There is absolutely no reason why roster sharing cannot be cross-platform, especially if we can already play across PlayStation and Xbox. I create teams and players in the ice hockey leagues local to me every year. They are popular with the players that actually play on those teams - however, because many of them play Xbox and I create and play on PlayStation, they're ostracised simply because EA, it seems, can't be bothered to make such a feature work.

So, my question: will roster sharing be cross-platform (even if it comes in a patch), or will we be left stuck in our respective console universes for another year?
