Even though it's not region free, most games have been released for pal anyway, just awaiting warioware
WarioWare was released in Europe before it was released in the US...

And I don't think not allowing other regions to play is that much of a mather and I don't think other chips released soon will allow other regions as well, maybe the later ones.
Basically all the chip does is making the DVD-reader think it's a real game and not a copy, so if it's from another region, it would believe it's real, but the Wii won't play it anyway because of the default region lock. If they wanted to allow other regions as well, probably more has to be modded than just the drive, to allow the region to be made valid and perhaps that can be detected by Nintendo. (assuming they really can't detect this mod)
Also, what's with people saying Zelda is the only reason for buying a Wii at this moment. Sure, it's the greatest game atm, but how long is the wii out now? More great games will follow, like Mario, Metroid, SSB, perhaps another Zelda, etc. And actually, I think some pretty interesting games are also out already, like Rayman Raving Rabids, Super Monkey Ball, Red Steel, Wario Ware, etc.
It's sort of like saying people only buy a 360 for Gears of Wars, cause how many games with the quality of Gears of Wars have been out for the 360? And that console has a year ahead on the Wii already. (Not that I liked GoW, I bought it for Rare's stuff
)
