In the unlikely event that IBM actually includes all of the features of JES3 in JES2, then I think that it will be stronger, albeit with a painful transition. If they do as they have so often done and provide only partial equivalents, then it will be negative.
I'm assuming that, e.g., user exits, user-written DSPs, would need to be written from scratch even if IBM does it right; that doesn't bother me, although it will be a royal PITA for some. -- Shmuel (Seymour J.)

I think that for a core part of the mainframe platform rationalizing to a single standard configuration of the OS from two options makes it more sustainable. Vendors and IBM can avoid duplicate investments and customers can better rely on pervasive support by software and an increase in the available supply of skills to operate their systems. In my opinion IBM should have made this definitive choice sooner this amounts to acceptance of prevailing trends.
