A couple of points directed at the OP...
The design and implementation of a product that is in constant dynamic flux as all massively multiplayer games are is never "complete". There are three primary factors that influence the moving target of implementation:
1) Technology
2) Design Concept
3) Customer
Technology improves rapidly in this industry and HTC does a fairly good job of keeping pace with those changes without creating prohibitive minimum system requirements that would disenfranchise large swaths of customers. Limiting technological factors that plague the game today may be resolved tomorrow. So, the incorporation of changes to accommodate those types of technological innovations that cast off restrictions are far more important than updating graphics to make full use of the latest/greatest video cards out there, for example.
The design concept is like the Wizard of Oz behind his curtain. We can only assume by the current implementation to what extent it is still a work in progress. If I were HTC, I would have short, medium and long-term goals to improve, modify and update design concept changes. A lot of those changes would be "on hold" pending technological advancements and integration. I would imagine HTC does in fact have some kind of list along those lines.
Then of course there's the customer. This is where it gets tricky. Because, while I say, "The Customer", which is how it looks on paper, in reality there's 10,000+? people who feel they are, "The Customer". Everyone's expectations and perspectives of the product are different. Even more complicating is the fact that a lot of what some customers may want conflict with current Technological limitations and/or the design concept. While some "geeks' may fathom their future expectation is currently out of reach technologically it is understandably unlikely they would know whether their future expectation is in direct conflict with the designer's evolving game design concept..
So, while there's no doubt HTC listens to their customers, as they have categorically proven. It is not as simple as, "Your wish is my command, sire". There's mitigating factors, "The Customer", is completely oblivious to for the most part. That being said we do owe it to HTC to keep them informed of what we'd like in the short, medium and long-term for possible consideration and inclusion on their "magic list".
