Any older stern that is selling at a current retail price or higher could definitely be considered for a vault.
A tron premium, tspp and lotr with the new lcd screens would all be amazing. Although with sterns current backlog do they really have time to do this and would they even bother if there’s only potential sales for 500-1000 units of each?
Also no way anyone at stern would ever say they are done with vaults. Hopefully one day they rerun some of the old solid states at say the home version pricing.
