So Switzerland have completed their National Final process. Also with their confirmed National Final dates or performers are: Albania, Belarus, Belgium, Bulgaria, Cyprus, Denmark, Estonia, Finland, France, Germany, Hungary, Italy, Macedonia, Malta, Norway, Portugal, Serbia, Slovenia, Sweden and Turkey. Not forgetting Azerbaijan as host nation. This gives us a total of 22 confirmed participants.
The following are listed on Wikipedia as participating, but this should not be taken as 100%, as their sources are not always correct. These countries are: Austria, Bosnia & Herzegovina, Croatia, Georgia, Greece, Iceland, Ireland, Israel, Latvia, Lithuania, Moldova, Montenegro (Returning Country), Netherlands, Romania, San Marino, Spain, Ukraine and United Kingdom. If all these countries are to participate, this would bring the total up to 40 participants.
Although unlikely to happen, Morocco is rumoured to be making a return after their one and only participation in 1980. Possible withdrawels though are coming from Armenia, Poland and Slovakia. There is no indication on the situation with Russia. If all these countries were to participate in 2012, we could be looking at a record breaking Participation List of 45 countries, although realistically we should be looking around the 42 or 43 mark again.
