Evolution of EM by maps by Márcio

I had some little free time, so I made the history of Eurovision Memories in maps. So, let's start:

EM08: EM returned to his origins, broadcaster from Bucharest, Romania. Small changes of countries this edition.

EM10: Cyprus hosts this edition in Nicosia and Latvia returns after 8 editions out of the contest!
Debuting Countries: Switzerland, Bosnia and Herzegovina, Andorra, Monaco
Returning Countries: Slovakia, Serbia, Latvia
Withdrawing Countries: Ireland, France, Belarus, Slovenia, Croatia

EM11: This time, Helsinki, Finland hosted EM with many old participates returning. This was the first year that had Second Chance Voting. The light green countries are those who passed that.
Debuting Countries: Portugal, Albania
Returning Countries: France, Ireland, Germany, Poland, Croatia, Estonia, Moldavia
Withdrawing Countries: Russia, Bosnia and Herzegovina

EM12: At this time, this was the edition with more participants: 35! Russia hadn't gave points for the semi-final, so it was desqualified.
Debuting Countries: Belgium, Luxembourg, Bulgaria, Lithuania
Returning Countries: Israel
Withdrawing Countries: Andorra, Switzerland, Hungary, Russia

So, as you can see, we still have some countries which never debuted: Malta, Austria, Montenegro and Macedonia.  Vatican City,  Liechenstein and San Marino would be more difficult, unless the nationality rule would be lifted for these countries.
Some questions:
 - Should Kosovo participated apart of Serbia? Some contests already allow that.
 - As we are a kind of "copy" of Eurovision Song Contest, shouldn't we allow the northern african countries and those from the Middle East who are close to the Mediterranium. The ones I'm talking are Morocco, Algeria, Tunisia, Lybia, Egypt, Jordan, Lebanon and, in other case, Palestine.

It was a point to discuss, but I'm sure we'll decide the best way.
