Ireland? No way. As Andrew has said OVER and OVER, there is a lot more to becoming a test nation, or even a decent associate, than playing results. On top of that, Ireland have scored two wins and a tie from one World Cup, and suddenly they are worthy of Test selection? Kenya made the Semis last time around and they still haven't been awarded Test status, so why? Because they do not fit the other criteria, and because one tournament is one tournament.
I highly doubt Ireland would beat any current test nation bar Zimbabwe (who they most likely wouldn't anyway) right now if they stepped straight in, they aren't even second overall behind Kenya; Scotland is overall still a better side, and were in the toughest pool there was, the top two ODI nations pre tournament, whilst the Irish's only real amazing victory was against Pakistan, they lost to the only decent side in their pool, and tied with the worst side in test and odi cricket out there (barring associates).
Kenya is not too far off from their playing results, but they are still not there yet. We must wait until the real evidence is present, and the sides can do more than just upset a few lightweights at one World Cup each. Obviously Pakistan are no lightweights generally, but they were not too great at the WC.
