Nope, I am too, this issue even took "Brexit" to the backseat of my interest and curiosity with foreign affairs. Both are head-shaking matters, but Brexit remains firmly within the economic realm, while the Catalan "procés" is very likely to escalate to a much more serious problem, if discussions stop within the confines of the established institutions and are transferred to the populace.
I've following the news from the "el Pais" (Madrid, but pro socialist, so it is both anti independence and anti Rajoy) and the "La Vanguardia" (Barcelona and all for autonomy, but not aligned with the ones seeking catalan independence now).
I think Rajoy will assume direct rule but in a step-by-step manner (money, law and order) and will leave the institutions void of any particular power, but untouched. And he will call elections, there's a general feeling that the Independentistas went too far and lost popular support, also that reality sunk in many hot headed people that thought independence was a troube free one way street. All major corporations left Catalunya in a move that is still only a formality but if Independence is declared will become very real.
I just hope the more radicals - and there are many - among the indep camp do not turn to violence in a desperate attempt to create a chaos that would, in their view, justify some sort of intervention from the outside. Good luck with that, Spain is a democracy, with laws, courts, elected parliament and accountable governemnt, a EU member, nobody will intervene like if this was a desintegrating Yougoslavia.
