I just spotted this on Screamscape which is an interview conducted between management at LWV and Valley Mania and it suggests that The Ultimate may be extended to make it the worlds's longest roller coaster yet again.

Is LWV still planning on giving The Ultimate renovation work in the near future?
Yes.
Would you ever consider extending The Ultimate to make it the world’s longest rollercoaster yet again?
Yes we are considering this, it would be useful to get some feedback on what riders might like to see and experience.
