I have details on the recent firings of Sylvester Terkay, The Basham Brothers and The Gymini.

WWE had high expectations for Sylvester Terkay because he was being groomed to feud with The Undertaker in a headline program on SmackDown. But after a few weeks, WWE didn't think his MMA style in the ring was getting over and they wanted him to do a pro wrestling oriented style. He was lost with the new style and was subsequently sent to WWECW. Also, Gerald Brisco, who loves amateur wrestlers, wanted to make him into a Kurt Angle-style wrestler. He too gave up on him in the end and that led to Terkay being dropped. Terkay's pro wrestling career seems to be over because he is now looking to sign a multi-fight contract with one of the MMA organizations.
There was talk of bringing The Bashams back to SmackDown once Danny's torn biceps injury healed, but that obviously never came to be. Apparently, the call-up of the more colorful, yet far less skilled Deuce & Domino act led to The Bashams being expendable.
Back in May, Todd Shane (Jesse Gymini) tore his pectoral muscle, which meant he was going to be out of action for a few months. His injury healed up by the fall season and WWE were planning to bring The Gymini back to SmackDown with Angel Williams as their manager. They worked a few tryout matches before SmackDown crowds back in November, but apparently, WWE officials didn't like what they saw because they probably would have otherwise been on television by December. Soon after, Angel was split from the group in Deep South Wrestling and of course, The Gymini were soon released. To show how little long-term planning was done in their departure, they were still the DSW Tag Team Champions at the time of their termination. They were stripped of their titles the very next day and never mentioned in DSW ever again.
