Momentum is picking up in the Pacific Northwest for a potential new Sonics arena that would be located on land owned and built by the Muckleshoot Indian Tribe.   SonicsCentral first reported on it here and this afternoon the Puget Sound Business Journal released a story about the feasibility study run by the Tribe on the cost and potential of a 18,000+ NBA capable facility.

Given the existence of a completed feasibility study, it would not be surprising if talks between the Sonics and the Tribe are at an advanced stage with an official announcement any day (pure speculation on my part however).
