The last polls are showing the gap between Syriza and ND widening: 33.4% : 26.7%, with GD, PASOK, The River and KKE all round 5%, others 3% or less.
Looking in to it further a single party needs 41.4% of the vote to get the bare majority of 151 seats including the extra 50. So a further coalition would be needed. Assuming this isn't Syriza and ND (LOL!) Tsipras would need PASOK and who else?? KKE resolutely refuse to join a coalition which remarkably would leave only Kinima (Movement of Democratic Socialists) but currently they are under the 3% threshold, so possibly they might end up with the newly formed River party if they would agree. The Independent Greeks are to the right of ND and would not support Syriza.
Syriza have dumped some of the more hostile anti EU policies and have focussed on relieving the effects of austerity for the most severely affected under the slogan"
[Edit:] Hope is Coming", plus taxing earnings over €500K at 75%, and negotiating a debt default. They are promising "no U turns", and it will be interesting to see what the prospect of coalition government will bring.
For the poll results in Greek plus further analysis including the shifts in voting intention that have brought about such a remarkable move to Syriza (9% from GD amazingly) see:

They showed an interview with a grape farmer in Assos (not the Kef one!), not at all a natural leftie. He talked about the impact of land debts on himself and his neighbours and the likelihood of the banks calling them in. So it's not just the urban poor.
