This case will settle, they always do. It's just not worth it (for the plaintiffs or AMD) to go to trial. In the settlement they'll pay attorneys fees, a small amount of money to the lead plaintiff, and promise never to do it again.
This kind of case is pretty common. A company announces [bad news], the stock drops, and someone sues saying that when the company previously announced [good news] they bought, or at least didn't sell, their stock. If they had known about [bad news] they would have, but since management misled them they lost money. Plaintiffs attorneys race to find someone who might have lost money to serve as lead plaintiff, and then race to the courthouse to be lead counsel.
Make no mistake, plaintiff's attorneys are in the drivers seat. They probably spend most of their time on cases like this It's a fairly standard securities case, where there's a decent chance the lawyers on both sides have litigated the same kind of case against each other in the past.
To win the case, plaintiffs would have to show that AMD made statements that they knew or should have known were wrong. Forward looking statements, like forecasts, are very hard to show were wrong. But facts about the current status of something is susceptible to direct proof.
Now that the lawsuit survived a motion to dismiss, the plaintiffs will get discovery. The motion to dismiss is resolved on the basis of assuming that everything the plaintiff has asserted is true, and then asking if the plaintiffs have a case. There are detailed facts that the plaintiffs need to allege to survive a motion to dismiss. While this is a real barrier, most plaintiffs attorneys are pretty good. They don't much bother if they don't think there's a case that can at least survive a motion to dismiss.
They will be entitled to documents relevant to the case (email, memos, reports, etc.) and depositions of the relevant people. The precise contours of what they get will be negotiated by counsel, and ordered by the court if they can't work out something reasonable. (Practice tip - judges HATE having to work out your discovery disputes. Be reasonable and work something out yourselves.)
Somewhere during this phase is where the case will most likely settle. Maybe after the document discovery is done - often plaintiffs attorneys want to do a fair bit of that phase to prove they did the work (and justify the award of attorneys fees) and defendants want to settle before having to do depositions of executives. Possibly it won't settle until after discovery is complete, and there are motions for summary judgment. Likely we won't hear much of anything until a settlement is announced, though.
