Don't think I agree necessarily, as it's been said they can't book a festival solely with major names and need to try and fill out the undercard too.
Still at least one headliner to come, plus 7 more bands in this advent calendar alone (last year they announced 10 on the 24th so might to the same this year). Couple that with the fact there's 15 or so bands to be added to the Sunday and then still probably another 10/15 international bands to come at some point in the New Year (as well as 2 dozen CZ/SK artists) then its probably still great value for money all in all.
Out of interest who are people expecting still to be added? I've honestly got no clue for that final headliner slot (outside of possibly Massive Attack, KOL or FIR). I thought Weezer might be added since they announced Bad Nerves on Sunday, they seem to be supporting them everywhere/would fit with the rest of the bill, would be a major bonus for me.
Most of those bands are selling well the headline concerts in the Czech Republic and except Slovak band Horkyze Slize, it's a good booking. Probably the strongest calendar they ever had. A7X are o2 arena level here as Slipknot, so probably a similar price... Lorna Shore, I don't get the hype, but they are billed high everywhere. Refused's last tour won't be cheap.
