Okay, checking a couple sites out, and found some information about CC1, and specifically the entries to the competitions.
As you'll be aware there's some "discomfort" about the pre-selection of entries into the compos, but this translated text could give some good news: "...jobs for other Competitions you can bring with yourselves and to hand over prior to the beginning appropriate ZX Compo without any limitations."
Okay, I think you get the idea (don't you love translations!?). Grabbed this from POS, it's some news from a couple days ago. Basically there's a lot of AY-tunes entered into the competition so far, but it looks like the other compos may go ahead without pre-selection. Did I read that right?
As for the entries into the categories, I grabbed this from Scenergy:

• 32k Game - 1 entry
• 4k intro - 2 entries
• 512b intro - 3 entries
• ZX Gfx - 30 entries
• AY-Music - 26 entries

Well, that's a fair few AY-tunes to sit through. Wonder if they'll all be released after the party?
