I wouldn't read too much into that, a lot of the old DSA flights have just been "copy/pasted" into EMA, most likely to allow existing DSA customers to rebook. The schedule will be refined over the coming months.
I'd imagine EMA could get a fourth based aircraft, possibly with the addition of some extra third party flights from the likes of Freebird and Air Europa, but would be surprised if it's any more than that.
