I am currently working on my Bachelor's of Science in Advertising degree, and in our Bus 101 course, we were instructed to highlight a specific business, and work on a mock business plan. The business we chose had to be one we are very familiar with, and would one day like to work for. Of course, I chose Arenanet. Now I am in Bus 121, and continuing with Arenanet, I have reached an assignment that takes me out to find a 'focus group' and throw out some ideas to get consumer opinions on. Consumers such as, well, everyone here at Guru.
The idea here is to find out how to basically make more money for Arenanet in this lull period before GW2 (which could conceivably be 2-3 years away - a large lull period for any business, especially video games). The online store and expansions onto GW are probably the top ideas, with brand awareness and merchandise down at the bottom (more people knowing about Anet and GW isn't likely to make their numbers jump dramatically). Online store expansion is what I want to focus on as a primary strategy, and there have been many ideas in Sardelac and now with the BMP promotion on how this could happen. I want to consolidate these ideas, stir up an environment to come up with more, and discuss them with everyone to help make some of this possibly happen, and find out if it's worth it - with the end goal of a good bit of info for my assignment

tl;dr version - Let's talk about what in-game content we would like to see in the in-game store. This helps me with my project at school, and helps Anet better serve us!
Some things to consider:
BMP being offered as a separate purchase - these threads are everywhere, which leads me to believe it would be very lucrative for Anet to do this. USD $5? $10? Should this be delayed for a bit to retain a certain amount of 'specialness' for those who bought into the promotion? How long? A month? 6 months?
Weapon packs - basically things like the "Game of the Year" weapons. /bonus and you get 7-10 new-skinned items customized and stuff. USD $5, just like the GotY items.
More mission packs - More stuff like the BMP purchasable for what, USD $10. Problem here: would this pay off for how much coding/art/etc that would need to be accounted for? Something to consider, especially if enough people like the idea.
Skill packs - Not what we already have, but a small pack of about 100 skills (what GW:EN was released with), no elites. Something that would be easy to balance (hopefully). USD $5
What else? More storage? Festival hats? CE-like special dances/effects? Any problems/concerns that could be had with this? Discuss!
