As for adding GPU support, I kind of hope that they don't untill much later.
It's nice having a coin you can profitably mine with your CPU whilst your GPU(s) mine something else.
If they add GPU support then CPU mining may soon become unprofitable.
This is a problem, as you do not have the keys for your wallet. So the coins are not really yours. They have the keys for your wallet.
The fact that they are not releasing an actual wallets is a big concern.
OK, just noticed that they are coming out with desktop wallets. Hope they are actual real wallets that operate in the blockchain.
