I used to work there, was on the PS2/XBOX FOBOS team before the layoffs started. BIS was working on FO3, they are all gone. The people that worked on the original Fallout titles have been gone for years now
Interplay will continue to sell its property, the Fallout license will probably be sold to the highest bidder. They need money and have no new games for this year. Their parent company VU Games is hurting financially too. They just had a bunch of layoffs.
Sad times for Interplay, it hasn't been the same since Titus took over and pushed Fargo out. Look at where Titus is, I'm surprised they are still a company. I think they have about two people left in the France office.
I was at Interplay for over 7 years. The company has been in trouble for the past few years. I doubt they will survive past 2004. Everyone still working there is actively looking for a new job.
