You're damned if you do and damned if you don't...
First about the region lock. Wii is region locked, 360 has optional region lock and PS3 is region free, but NTSC PS3 doesn't play PAL games on PAL TV.
About that PAL 60 mode, even that it is 480i/60, it's not the same as NTSC, it still needs the PAL color input. Every Widescreen TV should support this, and according to the poll in everybody votes channel, more than 50% of Wii owners still play with 4:3 TV:s, so the standard PAL localisation is needed.
Now, when people blame Nintendo about fucking up with people about the releases, it's the same thing with every other company and besides, only EA matches the quality or quantity of Nintendos localisation. First game ever i had seen with really put effort to its localisation, was Shadowrun, its Scandinavian version had swedish as language, and it really pissed me because i don't understand swedish.
The languages they translate the games are german, french, italian and spanish. Some games like Harry Potter, have had even finnish translations. I find it funny, that at the same time people complain about region coding, others complain (sometimes even the same people) about games not being localised enough.
In one way around, region coding is caring for the customer, and it really helps the publisher, since the financial issues are the main reason for region locks.
They do can release localised games simultanously worldwide if they want to, but the reason why they usually don't, is financial.
Like Onna said, it depends highly on the publisher when they get games here early. This is the problem with every console. Console being region free, helps the people who import, who by the way have their consoles modded anyway, but importing also hurts people who buy their games from local retail.
Looking at Sony and Lik-Sang, really shows what they mean with region free. Maybe it wouldn't have happened if PSP would have sold better, when the market (for Sony) would have been enough to support retail and import. Sony, its importers and retailers lost a lot of money with Lik-Sang, and therefore Lik-Sang had to be terminated (i hope you all see how humorous i am. Ha-ha).
Btw. how long did Metroid pinball take time to arrive Europe?
