but when will the miner arrive? Miners need their hardware NOW! we deliver in the US in just one week and the rest of the world in just 4 weeks max.!

0.5 BTC is a very good deal. with a bitcoin price of $580, that's just $290. Try buying a GPU for that money and see if you get it to even close to 1 MH... The G-Blade has almost 6 MH/s.
