Well, that's called marketing. They clearly chose to follow the marketing campaign of any big studio. Plus, it has been said that they'll stay with TB settings, so their word is even weaker that way. If they'd say we go for a RTS, or back to ARPG to concurrence Diablo one more time (which would give your quote some sense => why did they start with a Diablo-like if their dream was a TB game? And make then another one, then Divinity II and then Dragon Commander... that's nonsensical), or a concurrent to Witcher, Fallout, TES... Overall, their statements don't make much sense those last years. Since Tencent is in, they behave like any other major studio.
Considering how pornography and sex sell worldwide, there was no risks taken including those. Quite the opposite. The fact that the industry isn't much into sex so far is a sane thing overall, it isn't that polluted by society's standards that much yet. As for races, it's not like we could already play non-standards races in other D&D titles. I'd say they could have bring a lot more. Gith being playable makes sense considering Gith play a major role in the game. I find Dragonborn a more interesting choice, and they used it in a clever way overall, especially with Gith.
