Rumors. Do the prices begin to slide down?

Actually I don't like a rumors, but... At the December biggest construction and development companies suddenly have withdrew out from the market most "hot" offers - 1 and 2-rooms flats. And we've expected their selling at spring time with much higher prices. But for unknown reason they has become to sell them now. Something happened? Do they feel an overheating on the market? Or they have know something that we don't? Anyway, unpredictable moving is strange...
