Ospreys chief executive Lance Bradley has met with fans today to talk about a potential move from the Swansea.com Stadium.
It has been the Ospreys' home for almost 20 years but the capacity of more than 20,000 has become too big.
Options will be considered in Swansea, Bridgend and Neath with the hope to be in the new stadium for the start of the 2025-26 season.

Good afternoon and thank you for joining us as Ospreys host Ulster at the Swansea.com Stadium.
Both sides are back in league action for the first time in six weeks.
Last time out Ospreys defeated local rivals Cardiff and are currently eighth in the table having won five of their nine games in the URC this season.
Just three points separate the Welsh side from Ulster in fifth place.
Ulster claimed a memorable win on New Year's Day against Leinster in Dublin but have disappointed since in European action with heavy defeats by Toulouse and Harlequins.
Both sides will be desperate to get back to winning ways today.
