i dont think you will need to bother with NTSC this time around. Here is why:
At my local EB a number of months ago i noticed PSP very prominant at the front of the store. I thought that it cannot be their highest seller as the DS is meant to be destroying so i checked with them. Sure enough, the DS was killing the PSP, so i asked why was the DS not at the front of the store.
Their answer?
Sony gives us more money.
Now fastrack to last week (and if you have been to an EB recently they always should be the same) DS and GBA right at the front of the store with a massive reserve space also at the front of the store for Wii. I talked to the guys again and they said "The email came through to change all shops to this way, so we did, our guess is Nintendo is starting to throw their money around".
I personally see this as a good strong move from Nintendo. Maybe the PAL market will be ok this time around.
