News reaching us all the time here at Politics Cymru.
Sources have told us the 4th seat really is too close to call.
It could go to Labour, to the Conservatives, to Plaid, the Lib Dems or UKiP: "it really is that up in the air," said one source.
"All bets are off," said another who actually reckons UKiP could well be in the driving seat based on local elections results in England. The three main parties are going to take a kicking from the electorate, he said, and it's likely voters have backed UKiP out of protest against the mainstream parties.
Interestingly he claimed Labour have no chance of getting a second seat.
What are your thoughts? If Plaid takes the second seat from Labour will that have an effect on the One Wales coalition in Cardiff Bay? If UKiP gets a seat does that show people don't realise how much Wales has benefited from Britain's membership of the EU?
