There is no time frame for the Fiat gateway, as was made clear by the team from the get go. They did get rejected a lot by financial institutions because most don't want to deal with cryptocurrencies but here's a quote from the newsletter
Fortunately, Jan and Roger built a great relationship with ING Bank Netherlands after a few live meetings and a lot of phone calls. ING Bank is willing to look at our request. As soon we have more to report about the progress on this subject we will share that with the community. The plan is that ING Bank will accept us as a customer so we can provide iDEAL payment options and other services in our Mobile App.
