Why? Whoever pre-ordered can pay now and get it for the price that was initially mentioned. The rest (me included), we still have a chance to pre-order and pay to get it for that price. If we don't....... well, we knowingly missed our chance.
I mean 650€ is a lot of money, but if I can spare 650 for a phone than I can spare HYPOTHETICAL 750 also. The only thing that kinda worries me is that this 650 was the price mentioned everywhere and as much people loved the idea of HWK phone they didn't like the price. So I hope that POTENTIAL price hike won't drove away many of those that were interested. Outside of this forum anyway.
