Im on the verge of ordering a Wii Key, but am wondering if I should wait for the next gen chips. Realistically, how far can they go with the current WiiKey with firmware updates alone? Is is possible to have full NTSC Playback on PAL consoles and vice versa with just a firmware update or is this likely to require a new chip? Also, is it possible to say remove the WiiKey and install a next gen chip in about 6 months time? Many Thanks.
