Dime has kept Dean relevant, literally. Dean has been milking his name for years.
Fuck Dean. Evan is a douche, their guitars are average at best, (aside from their top-notch Custom Shop that does next to nothing these days).
That said, I think the lady's grasping at straws. If they owe the estate money, get it. But aside from that, cut your losses, and stop depending on Dime's name to put money in your pocket. That goes for Dean as well.
As for future models? Dime was Dean. Seeing another brand producing Dime models would be stupid, and only prove it's a cash grab for the "estate". Is it about his legacy? No. Its about cash in her pocket, plain and simple.
