I am an electrical engineer that designs a lot of audio stuff including guitar pedals. Today manufacturers certainly would go digital for chorus/flanger/delays unless the appeal of analog BBDs is directly what they are going for.

Digital has one advantage: your one PCB design can become many different pedals. Just change the design of the case, maybe leave the RAM IC out in effects that don't need a lot of memory, put different code on it and congrats: 90% of your product range are the same PCB and the same parts which is nuch more economical than doing a new design for every product.

Exception: Fuzz, distortion, overdrive and everything where you rely on complex characteristics of affordable analog parts.
