I'm a diehard D&D fan, and I'm currently on Eberron campaign on pnp... I'd love and I assume most players, to get at least 2 more Eberronian continents to explore, like Khorvaire (Interesting lands) and Argonnessen (For the Dragons). Before Turbine does that, why not let us explore Xen'drik to it's fullest, go to other cities besides Stormreach and explore the famous Mel' Akat in the Menechtarun...
What would the rest of you guys like to see come to DDO in terms of expansion
