Well I think it is the opposite.
The blue displays, bells and whistles is what has been selling, Magnum 257 for example.
The 2950DX has been out awhile, with no changes people lost interest.
The 5054DX has a blue display, put that on the 2950DX and advertise it with the new mosfets, I bet it sells quite well!
People like to see changes thanks to the cell phone craze! So they expect it in the radios also. Thats why the Magnum radios are selling, and offer SSB.
The manufacturers can't sell the SSB radio it if they don't build it the way people want it!
