Winamp supports FLAC,
VLC supports FLAC,
Nero supports FLAC through a free plugin,
SUPER transcodes FLAC,
BurnAtOnce supports FLAC.
Bottom line, FLAC isnt obscure anymore and people who prefer lossless media know what to do with it. I'd prefer to see a FLAC release (smaller file size) but a WAV release is alright too, so long as it is lossless.
