With Gulf air operating a Dublin to Bahrain and onward connections from there (including Dubai), this seems a little like stepping on someone elses toes. Personally I thought it would have made sense to head off to somewhere they could connect with CX or QF and interline pax onwards. Maybe that's next....
Not sure there is a demand for 3 a week to Dubai from Ireland though! And they are up against some stiff competition (even with the nessecity to transfer at LHR etc!)
