I Like your coin but it is way overpriced. Not a surprise that presale is not going as well as expected. I am hoping to snatch some coins at 200 satoshi after launch.
It's not reasonable to expect this. Something like this might happen in case of serious technical failure or similar bad news, but normally not. So likely you'll have no chance to buy below pre-sale price. And if the price really falls, you will have no interest to buy anyway.
I'm more afraid of low trade volumes and possible lack of interest in the coin and services, sort of "Mastercoin illness".
