unknown. it all depends on if wesker succeeded in reviving him.
Yes it depends really. At this moment he is classified as dead because he did die in Code Veronica. But Wesker hinted that he would more likely bring him back to life. Who knows if he succeeded as the previous person said. Right now we're unsure if they are going to bring him back, but if they do hope Claire finds out. It would make things interesting. We'll just have to wait and see.
