I think they will change each element to be non-compatible with previous versions
just look at WE7:I PC, it's nearly the same game as PES3, but they changed kits and boots structure a bit - for what? It doesn't make the game better than previous in kits/boots look
commentary idea was messed too, just look:
there are 5 data_x.afs, each is the same instead of commentary, each takes about 670 Mb, and each contains all 5 language versions
so we have: 5*670 Mb= 3350 Mb = over 3 Gb
only commentary inside each data_x.afs has about 250 Mb
they could make just 1 data.afs and 5 separate commentary files (eg. commentary_e.afs, commentary_i.afs, etc.) and it could take just about:
data.afs - 420 Mb
commentary_x.afs - where "x" - is letter of language (e, f, i, g, and s) - 250 Mb*5 = 1250 Mb
so all the game could be much smaller (about 2 Gb less); if they will be smart, they fix that and will make better commentary coz they will have more space available for this
I'm not waiting so 'hot' on Nack fifa commentary patch, I listened mp3 he relased and it was good but nothing special, coz I heard fifa commentary when I played fifa so it's nothing new for me. Maybe if someone would try to create his own english commentary as enjoyable as Japaneese commentary it could be more interesting...but it's just me
