Here's a statement [1] by one of the largest upcoming surveys, LSST. At least for them, this isn't going to be too much of a problem as,
1) Exposures are fairly short and frequent and so pixels contaminated by these satellites can be easily rejected.
2) There is a huge amount of resources (relative to other projects) going into the image pipeline for this project.
I don't actually know in details how much this will affect other types of observations though. [2] is the IAU's statement (that goes with that image), which points out some types of observations that might be more affected.
