As for the Timeline Neutrality discussion, let me point the following:
It's different to argue for a clearly defined time period when releasing the RPG ("The Emperor is now Iweko I, Spider are around and hunted like pesky arachnids, folks are fighting all around, alliances are X, Y, and Z"), and giving people an information dump (something that I think is what kinzen was referring to). The background in 4th Edition, previous and future ones, can, and has been, restricted to just a timeline with major events that spans 2-3 pages. I think that's easily manageable for everyone.
What I at least mean with my stance against timeline neutrality is that I want said time period for the RPG to be clearly defined... and to be assumed that said period -is- clearly defined. Not the half-and-half approach we saw in 4ed, where it was heavily hinted at the current time, but at the same time it was said it was timeline neutral. The "it's not fish, but also not meat" approach is something I personally don't like at all.
