I'm not sure if IBM acquires good products and makes them shitty or just makes shitty products from the ground up. I can't say how realistic it is they'll screw up Red Hat, but every IBM product that I've used in the last few years has been absolutely atrocious. At this point I just assume everything they touch turns to shit unless shown otherwise.
I hope that I am proven wrong since I actually quite like the RHEL / CentOS / Fedora ecosystem.
