I did read the report and am really glad SD continues to share. From what I've read here and there, this doesn't surprize me at all re:single player utilization. The great news is that as long as the game is selling like hotcakes, there is incentive for SD in continued support of the game. Additionally, I'm pretty sure that Brad mentioned before that he's more in it for the long haul. As in Demigod will still be raking in sales in the future as it will continue to be available for sale on Impulse and will be promoted via sales, etc.
As far as we poor folks who love DG for multiplayer, we're still getting clan support (no eta that I'm aware of), impulse is still slated to get VOIP at some point. Its really just a waiting game... which we are all used to (patch is coming out last week, today, next week). Not to say that any of us really like the waiting game, but SD being clear with why there was a delay continues to impress me.
I'm pretty sure that the vast majority of feedback for DG is coming from the small community of online players, so I actually do believe that supporting online players is still a priority. I don't feel like we're being dropped by SD in favor of single player. They could leave DG exactly as it now and they'd still see sales coming in, but we are still getting updates. My 2 cents.
