Sadly no. This would be a big hit, but companies have weathered bigger lawsuits than this.
The only thing that could conceivable 'destroy' EA (and wouldn't be out of the realm of possibility) is if it came out that they've been falsifying their financial statements.
We have no way of knowing whether or not it would be a big hit.
We have to see the contract that the individual had with EA. If he really had a contract giving him royalties on any derivative work then he should absolutely have been getting paid, even if the game no longer included his code (depending on the exact working, as phrased in the article here it just says derivative of the game and not code, which indicates sequel IP titles).
It being a big hit depends entirely on the amount of royalties specified in the contract. FYI, it doesn't matter if he was "just a contracted" developer or if he NEVER worked on site. All that matters is the terms of the contract.
He's demanding $4 billion in profit, but that's just silly. The most I'd expect is him to get is his royalties plus interest and perhaps some damages for breach of contract over all this time. In any event, it will really just depend on the actual royalty number. If it'd just get him something like $40k in royalties then I'd hardly expect to multiple millions getting thrown his way unless the courts want to punish EA for this if they've been in the habit of doing this. Otherwise, I don't know if punitive damages would really be up for grabs in this case. In this event, him demanding $4 billion dollars would be a little like me suing a hot dog stand for all their profits because he failed to give me a condiment with my hotdog even though I'd asked for it.
