The intention is to bring in extra revenue although nothing about the figures has been revealed.
In that sense you can understand why clubs would be interested in view of the reduction in central funding and the new Sky deal being only for SL clubs.
Apart from the funds coming directly from the TV deal I'm sure club sponsors both existing and new would be far more interested if they thought their companies / brand would be getting a few hours of TV exposure.
On the other hand some of the problems associated with Monday / mid week night games have already been mentioned and there will be a few more to add to that list.
