The Boeing 747-SP just had an upgrade launch, meanwhile, the SP itself never did. So the SP needs to be corrected.
None of the -200 series have had any engine upgrades made available since the time they have launched, although the -100s have. But as other upgrades have happened without launches, maybe the engines just haven't arrived yet.
The -200M is due to launch sometime soon and I would expect now that it may not since all other -200 series B747s haven't launched as they were supposed to.
