Aside from casino work, I don't think USPC does anywhere near enough with their other band names. They're probably concerned about the solid name-brand identity of Bicycle, in the sense that when someone not in this hobby thinks of a pack of cards, they tend to think of Bicycles. It's the first brand that pops into my head, and it was all we used at my poker table. Personally, though, it sounds like USPC is taking all their eggs and putting them in to a single basket - named "Bicycle". They have awesome brand names both current and historical that really need to see the love some more.
Sorry if this is off topic a bit, but I think you've made a great point. It's one I've noticed as I dive more into card collecting. I know it's a lot of work for USPC to develop their brands, but I think with all the brands they have under them, they could divide up what each brand would cater to like retail companies that own multiple brands (low-end, middle-end and high end clothes). That could so easily work with Bee, Bicycle, Tally-Ho, Aristocrat and Hoyle that they have. I honestly would have jumped to get the Bee Serpent deck.
I'm sure they feel they have this already:
Low end: Streamline, Maverick (regional), Aviator (regional)
Mid-range: Bicycle, Tally Ho (regional), Hoyle, Arrco, Aladdin (regional)
High end: Bee, Aristocrat.
It's just that they're not doing much beyond simple, basic models for most of these decks, favoring instead just the Bicycle and Bee brands due to immediate name-brand and trademark recognition. Bikes are crazy-popular here, their best-selling brand, while Bees are their biggest sellers throughout Asia and in China in particular.
