Tyco apparently debated several different weapons schemes for the Brontosaurus before ultimately deciding to release the production version. It seems that Tyco spent quite some time mulling over the different options and judging by the picture of the Brontosaurus that was included in the miniature comic insert for the second and third series toys, Tyco had yet to finalize the design by that time.
What's interesting is that some of the designs that Tyco was considering were illustrated in the cartoon episode, "Battle for the Brontosaurus." In that episode, Questar asks Turret to show him some different design schemes that he had been working on. Several different variations were shown:

actual production piece, the prototype features several fold-

These show the same design that was chosen in the cartoon and so it seems that Tyco was pretty far down the road toward making this design scheme a reality.
