SaeedDev94 Well, 2 months passed and still nothing, we have some evidences now!!
I think the speculation was that the QPR1 source would be released when QPR2 ships to Pixels. If, as rumored, QPR2 will ship to Pixels near the start of December, that's a month away. I guess it is possible to claim that 2/3 of the necessary evidence is available. But if the QPR1 source is pushed this week, or next week, or the week after, I think the situation will be unclear until we see when the QPR2 source becomes available.
Who knows? Perhaps the QPR1 source will never be pushed, and the QPR2 source will be pushed instead!
The 1-deep-pipeline model is an interesting model, and perhaps it will turn out to be true, but I think we're a month out from having evidence supporting that particular model.
