All the releases in past took place according to plan without any delay that makes high probability that full version of exchange will launched at the end of this month. Exchanges with good services are climbing up in matter of days and demand of such platform is increasing everyday. Ironx has become popular before launch that explains many things.
I think it will be in Q1 but I don't think in January. If they can launch the exchange in January, that would be great tho.
