One reason (as I have asked them about this before) is that they brought out the PocketRocket/Titan Kettle Kit after the Jetboil showed they had a all-in-one stove solution. We believe that we already had one currently, but realized it wasn't being marketed properly. When we first introduced both products, we didn't originally intend them to mate together. However, we found that if packed right, they can be used as an all-in-one. However, they don't fit very well. I think what you will see this coming year is a revision in the Titan Kettle that will allow the Pocket Rocket to fit much better. I'll ask Redwood and Drew (two guys in charge of stoves for MSR) what's in the works. I might have to slip them twenty bucks <img src="/forums/images/graemlins/smirk.gif" alt="" />.
This was brought up in our sales meeting and the explanation was that they offer great ambient light in the interior. For next year, we are bringing to market the new Hubba HP and Hubba Hubba HP that include a bright yellow fly. I know that many of the reps weren't pleased with the color but after getting into the tent saw the reasoning behind it (great ambient light). The other reason, we were told, is that they are easier to find when the weather turns bad. Our new Venture line is more of a light tan and not so bright. I will ask Terry (our tent guy who used to be the head engineer for Moss Tents) for more specifics.
