According to ETK 2/2012, 1/2012 production 520i & 528i still use different blocks unless for low compression markets.

As you mention there is a normal and a low compression version depending on country options.
And some countries get different turbo chargers.
We will have to wait and see what version makes it to each country before we can make absolute comparisons.
All the info is not available yet and some has changed recently.
Different BMW models will also change engines at different times.
Lets wait and see
