Someone above posted that we could get another item piece called a "proto transwarp drive" and it gets us to the delta Q real fast, but breaks down when we get there. Then some delta Q species helps to repair it etc etc.
what likely happens is a variation of hi here's an experimental piece of kit but we won't tell you it's a one way trip to the delta Quaderant. Once your there , you discover your stuck. The solution will be in the form of a new reputation grind. Upon reaching tier 5 you get a new project to unlock called the real drive . this one works an gets you back home .
Now if cryptic smart they tie in the new reputation system for this grind via missions an stf's that only those in the delta quaderant can partake in . Thus giving you that whole "voyage" experience . After reaching tier 5 an making that much needed drive to reach home. it becomes a useable conduit for insta travel to an from for repeatable dailies an the usual round of farming.
and to make things more interesting that real drive . it'll be a universal console since we clearly don't have enough of those already :-)
