Hello PoP89,
We thought we could, but we're not sure yet, especially because Apple twisted what the european regulation asked for, in a way to pump even more money out of the developpers pockets. The european comission still have to check if its even legal, so if it happens, we will have to wait a while longer.
Besides, if Apple eventually opens to side loading, it will only be in europe. The rest of the world will not be that lucky.
