Heh, the PAL Wii didn't take Freeloaders even at 1.0 which is why my Wii has a GC sitting on top of it (well, not right now since it's in a transport box as I just came home from a vacation).
The whole point of region locking is to prevent the market from punishing NoE for being horribly slow in bringing games over and then charging WAY too much for them. Just locking PAL consoles won't work because then we'd import US consoles and play import games.
This is why Europe has it so bad, because the developers/publishers have to optimize the game for the region of Europe by translating and localizing it for multiple countries and get console games running well in PAL.
Pwahahahaha, yeah, like they spend any time dealing with that. To me it looks more like they do their best to do that job as sloppily as possible. PAL bars, anyone?
Unlocking the region doesn't fix the problem that the games aren't necessarily playable in all regions due to difference in TV display standards (PAL vs. NTSC), since yes, the system will either output PAL or NTSC by default, since the world hasn't been fully arse-penetrated by the standardized HD/ED standard yet.
Most PAL TVs handle NTSC just fine, the PS2's 60Hz mode consists of outputting NTSC (as opposed to PAL60 like the GC does) and all those import enabler discs seem to have no trouble whatsoever dealing with that. It's not like there's ever a reason for an NTSC country to import PAL games anyway.
