Yamaha seemed to find the time to get bikes together. It's just a matter of how bad they want to race.
Honda pulled out in 1988 too, leaving Rainey and Shobert without a ride. Rainey went to GP and Bubba ran a superbike with limited funds and still won the championship. the link below tells this and that Hodgson might run for Erion or Corona.

I'm sure other teams are look at riders like Duhamel and Disalvo for their teams. They might have to take a pay cut but it beats sitting on the couch while others are racing.
