It's not a day one for me, but the price isn't the reason. Voice chat is a non-issue for me as well.
I don't get the restriction to two stages that shuffle every few hours. I hope that is eventually removed or at least expanded to more stages or less time between shuffles.
Basically if I bought this game at launch and went into multiplayer, there would be one game mode with two maps to play on. Don't think that's enough variety to keep me hooked for long. Sounds to me like it only needs a few weeks to, uh, ink-ubate (I apologize for nothing). Splatfest sounds cool. Reminds me of the old Everyone Votes channel on Wii.
EDIT: One thing that would help, and I don't know if anything about this was clarified, is if the two active maps were different for each game mode. So if maps A and B are the two currently being used for Turf War, C and D are being used for Splatzones. If that's the case it wouldn't be so bad, though I still think it's a stupid restriction. But yeah then I could see the game being worth a buy after a few weeks, by which point it should have 8 maps on at least two online modes, and the first Splatfest would be starting.
