I'm reading some practice articles written in Japanese; not sure if they're based on real articles, but no matter.
The title in question is 村上ファン集うカフェで発表待つイベント, and I'm not 100% sure what the 発表待つ part is saying, thus I thought I'd ask.
It looks grammatically incorrect to mean, and I'm not sure what the title is saying as a result of this.
