What about it? You'll still have to use the 3rd-party Thomson plugin, just like you have to for all proprietry formats. Nullsoft already pays them for a standard MP3 Decoding licence, and aren't gonna pay them anything more - never!
My recommendation? Stick with .AC3 or aacPlus or .ogg.
Do NOT transcode!
Thomson/FhG fouled up once with mp3pro. Have they not learnt from their mistakes? Or is this new format also going to have the .mp3 extension as well? If so, then it deserves to die before it even takes off.
