Don't bank on the "oldco" ever re-merging. It's obviously impossible to say as nobody really knows the ins and outs but depending on many things, not least of all the tax case/ticketus it may be in the best interests of the creditors to wind the current company up and distribute what funds / assets are available. I would assume D&P would be retained in some capacity as already stated, they would not however be putting a full team, full time into dealings for a further x years.
