It's early days, don't get so worried now. Wait for what the US?NA may be receiving. The first XIII sold exceptionally well in that region, so SE may actually treat you nicely guys this time
Who know, the US may get the steelbook as a standard for the first press like they did for XII!?!
The Nordic Edition sounds more like an 'exclusive' for the Scandinavian regions [kinda like the exclusive editions that Poland gets]. I believe the 'official' 3rd edition will be available to all the usual PAL regions as it was announced last weekend from Australia that there will be 3 editions available. For all we know, it could the a custom console edition for the PAL region that Japan is already getting.
