Concept art said alot.
Additionally, I recall that during a game promo on Spike TV, the moment where Chris and Sheva confront Excella was shown. However, Wesker is protecting Exella this time and instructing her to flee and take the PG67A/W case with her. It is real, I promise, and it's most likely one of the unreleased hidden scenes from Capcom.
