How much is the gap between the richest and poorest countries in the EU expected to close in the next decades?

Slovakia and Lithuania had fastest growing income recently, but even for them growing from 50% EU average income per capita (in purchasing power standard) to 70% EU average took about 6 years. Bulgaria and Romania haven't reach this level yet.

I predict that in 2023 France, Germany and UK are below 120%, 2004 enlargement is at 70-80% and Romania and Bulgaria still below 70%.
