Wow, stupidest article I've read today. If Intel joins the race, there are three likely scenarios
1. Intel will ask for premium price and got wiped out because gamer is not OEM buyers and will care about price/performance
2. Intel competes with ATI and Nvidia at the same price point. Meaning sell their card at whatever price point set by ATI and Nvidia at the time of Larrabee's release.
3. Intel set Larrabee's price lower than existing ATI/Nvidia cards to gain a market share. This will force ATI and Nvidia to lower price even more to try to squeeze Intel out before it gains a foothold.
Neither scenario is good for the downstream card markers.
