Lack of Bump Mapping and other Graphical Enhancements

I was originally very excited about the graphical enhancements of the new login screen of Guild Wars. The bump mapping and the heat distortion in the fire looked like they would be welcome additions to the engine. But I was extremely disappointed when I played the Nightfall Beta and these were completely missing from the game. The only real change I saw were the doorways, and those I can take or leave. It's really not all that hard to add bump mapping to a texture, and it obviously looks very good with the Guild Wars engine, so why not? Lack of time, money, or interest?

Good question; I was looking forward to that as well.

Any answers from the Devs?
