GM To Scrap Pushrod V10
For performance applications, this is probably the right move. The LS2 is a heck of a motor at 400 HP, and only 7-8 lbs of boost would be required to put it at 600 HP. That'd be a beast under the hood of a CTS-V, or in a Silverado SS.
The V10 was also proposed as a replacement for the supercharged Northstar, which is currently offered in the STS-V and XLR-V. Hopefully, the idea of replacing those engines is permanently dead. I can't imagine that such an idea would have resulted in a better product, or improved market acceptance.
My concern with this decision is that the pushrod V10 would have also replaced the dreadful 8100 big-block V8 in heavy-duty light-truck and medium-duty truck applications. I don't think that a forced-induction engine requiring premium fuel would find much acceptance in the commercial market. Now, GM may be betting that diesels will replace large-displacement gasoline motors in these applications, and I think that'd be a fair assumption.
