It was pretty obvious that the Celestial hardware was already pretty much done and Intel isn't going to stop developing integrated graphics. While it's always good to have official confirmation it was unsurprising.
I think the most interesting thing Tom said in that podcast was actually that Intel wants a 1 year cadence on graphics cores. Obviously from an integrated standpoint this makes sense as Intel releases new CPUs every year. I don't think releasing a full stack of SKUs in discrete every year makes sense though especially given how expensive video cards have become. To have that be viable they would need very precise sales data and given they're the new player in the market I don't think that's possible. Running out of a SKU that turns out unexpectedly popular could be almost as bad as cards sitting on shelves if new GPU cores were constantly on the horizon.
At the same time this could be a very real competitive advantage in the low-mid range segment. If Intel ends up turning out yearly increasing performance in the $200-300 range they'll likely sell every card they make for this segment.
As for future Battlemage SKUs I feel the same as bit_user unless there's a good reason to be keeping it to themselves Intel needs to indicate whether or not a higher end model is coming. CES seems like the time for video card announcements so even if they're not going to give performance numbers this would be the time to yay/nay on whether there will be something coming.
