Welsh rugby administrators are still hopeful their regional club sides will commit their future to the RaboDirect Pro12.
The Welsh Rugby Union met with representatives from the Cardiff Blues, Ospreys, Scarlets and Newport Gwent Dragons on Wednesday.
And WRU bosses emerged from talks at Swansea's Liberty Stadium confident they can convince the four regions not to force a breakaway to join the Aviva Premiership.
The continued uncertainty around the future of the Heineken Cup or a top-level European rugby competition of any kind has led to the Welsh regions looking seriously at an Anglo-Welsh league for next season.
English club governing body Premiership Rugby are exploring the idea of that cross-border league to fill the void left by their potential European rugby exile next season.
After a meeting of the professional game board in Wales though, the WRU issued a statement that points towards further talks.
Welsh union bosses do, however, expect a resolution before the new year.
The statement read: "At this key moment for rugby in Wales the WRU continues to work hard in the best interests of Welsh rugby as a whole.
"It would be unfair on the fans, the players and all of Welsh rugby to make any further speculative comment at this time.
"However, the WRU remains hopeful that the regions will decide to continue with the participation agreement by the deadline of 31 December."
