Umm some are and some aren't, Metroid Other M is different in PAL vs US (not sure after the delay), I also believe Sin and Punishment 2 is also different.
Interesting to note that the European date is still sitting at 11th June. Other sources are quoting the 1st July date, not sure what the long delay between the EU and the AUS dates is for (cant think of another title that would be in there to lock it up).
As for the BT date well.......... (have a look).
