I actually want more genuine Line 6 amps. Anything they could think of, really. If the HX series was stripped down to just the ones available (possibly somewhat improved here and there), I'd be every bit as interested in the Stadium as ever before.
Instead of tons of new or agourafied amps, I'd really love to see more dirt pedals, especially of the weirder kind. Or of the killer kind.
And I'd defenitely love to have a Line-Six-ified version of the Top Secret OD, should offer more output volume (it's really low at moderate gain settings) and ideally a 3 band tone control (a pre-boost tight switch/control wouldn't harm in addition, either). Defnitely my most used dirt pedal out of the HX universe, but I pretty much always have to pair it with an additional post-EQ.
The combination of the Voltage and a Top Secret OD is my "first grab" for anything dirt. Not the tightest sound by any means, so possibly not suitable for metal, but there's some stoner goodness to be had, with a neck pickup it's coming along kinda fuzzy/wooly, the bridge pickup then gets things somewhat tighter very naturally and it cleans up as great as it gets IMO. Add a bit of compression from a Vetta Comp and there's a great lead tone. And it works like that with each and every of my guitars. Even deals with somewhat more complexed chords absolutely well.
