A decade is a very long time. We don't even know whether test cricket will be played till then. Bangladesh got their test status in 1999. 24 years have passed and even now they struggle against the top teams. Overall, test cricket is dying outside the pig-4 nations. Even in South Africa and Pakistan, the situation is not very hopeful. The less talked about West Indies and Sri Lanka, that better. And regarding Ireland, I would still stick to my argument that they were given test status before they were ready for it.
This is correct not many teams are interested in test format now, even few are willing to play ODI. Pakistan lost 3 consecutive home test series and main reason is they are playing too much T20. The current generation who started playing or watching cricket in Era which is dominated by T20 so it's natural that they won't take much interest in test or ODI. The ODI world cup is approaching and I don't think there is any enthusiasm for that event.
