the situation in detroit is really sad.
as for your question, i've been to playoff games at the pond a few different years, and the atmosphere has varied. last year it was pretty quiet (but the ducks were playing horribly so there wasn't much for the crowd to be excited about), but other times it was pretty loud and fun. i think it depends on the opponent and how well the team is playing. against detroit, i'm sure it'll be pretty loud. i'll be there game 4 so we'll see.
