so this will be a gpu coin at launch?.

Q: So is it CPU only? Will I be able to use my Butterfly Labs ASIC when it arrives (... any day now...)?
A: Using Keccak as a hashing function renders current Bitcoin ASICs and the upcoming Scrypt ASICs useless on the coin. GPU parallelization of Keccak is possible but currently does not exist for mining with our implementation of SHA-3.
