On your first point, I do agree if that's the case. I'm just saying that people shouldn't be asking or suggesting that WotLK should be completely ignored because they feel that's what is happening to the other expansions that they play on. Would you wish what you feel you're going through right now onto another group of people? Nevermind that they are the majority of the community or that their development was completely ignored for over two years.
Anyway, I don't know for absolute certainty how much development is going on for Cata and MoP right now. I'm fairly certain there is at least some. But we do have a lot of content planned for you guys which we will bring to you through Lordaeron. Once Lordaeron reaches an acceptable level, we'll be porting a large amount of content over to Cata and MoP. Much of which will include some questing content, a lot of "old-world" dungeons, and perhaps even some raids (such as Ulduar).
We don't want to split development too much among the expansions until we're ready to do so, though. And that seems to be what a lot of people are asking for, or that we just simply abandon WotLK & Lordaeron (which we simply WILL NOT do). We have to wait until we're ready to do it, and being able to port content over from our WotLK core will make the developer's time doing this much much easier. Ultimately, we want to be able to cater to everyone at the same time, but slowing our development speed to a crawl is just something we can't afford to do. Surely you understand how splitting the development across each of the expansions would slow development as a whole, don't you?
The way I see it, we have to make sacrifices to truly move forward. If that means delaying fixes and new content to players on two of our expansions so that we can get the third expansion (the most popular and successful of the three) "out of the way" so we can better cater to the other two later on, then so be it.
You will get your turn in time. And when you do, we will make sure that the expansions you play on are just as complete as Lordaeron is.
