I could be wrong but I don't believe checkmate is workin on a new Zt 260. The new convincor 260 is still in production and the last I heard we can expect test results in this month. I know they are very busy right now so it wouldn't surprise me of we don't hear anything until mid June. I am more intetested in the 43 punisher completion myself.
Are you hoping to purchase a new 260 or just curious?
