Pretty sure there is, but that's where a multi-million company should use market research and marketing experts, not that Trooper knob from forums.
Hmm, I think for something to sell in enough numbers to justify it, it wouldn't be too hard to think of. The reissue pedals were like that - clear demand already there for them, and no significant R&D costs. Still - if you think there is something you'd like from Marshall that you can't buy yet, I'm curious what would it would take for you to rush to a music store and buy one. My impression is their market research and experts have told them to focus more on brand recognition and diversifying than investing purely in creating and marketing new products constantly.
I think they've probably hit a point where the returns on what it would cost make no sense at all. Would they really expect to sell huge new numbers of a flagship amp? What exactly will differentiate it from a JVM or DSL, or one of the classics?
Even in smaller quantities, whatever they design is either going to tread on the toes of something they've already got in production, or people will say "BUT IT DOESNT SOUND LIKE A MARSHALL". The Origin is not a good amp, probably went through a ton of R&D and headaches to get it to market, and it still does OK. But its absolutely the first on the chopping block because its made redundant by the studio series and smaller DSL's. They really could have just not bothered with that amp, and focussed more on the other lines.
Perhaps what they've done with the DSL line over recent years, where its had small incremental updates is probably the best they can do with their other products. They can continue manufacturing them in the same way, it wont tread on any existing products, keeps interest up and people know what to expect already. Wouldn't cost a bomb for them to implement better FX loops, MIDI, maybe an (optional) reactive load to existing products.
I'd personally LOVE to see Marshall's take on a Smallbox or Runt style amp, but really, would it sell that much to justify it? is it really going to offer something that a DSL or JVM doesn't already do? are people going to understand or differentiate between the differences? Would probably cost a lot to do, and end up confusing their customers.
