Meizu CeBIT shutdown wasn't for what you'd expect -- in a Meizu forum post, Jack Wong says that an Italian company called Sisvel complained about another Meizu PMP's unlicensed use of the MP3 codec, and that's what prompted the 5-0 to arrive. Interestingly, Jack also says that it's all a big misunderstanding, because Meizu products, including the M8, don't actually play MP3s, just WMA, and that local distributors have to cough up the licensing fees for MP3 playback. Apparently the booth is now open again, with the offending PMP removed -- the M8 remains on display, probably because it doesn't actually work yet.
