Well, of course, in a collaborative fiction line, there are always going to be options left open. Well, usually. But that doesn't guarantee they'll be taken. Heck, canonical Trek could have easily resurrected, say, Sito Jaxa or Geordi's mother, but it never did. It did resurrect Tasha Yar, but only temporarily, and then brought Denise Crosby back as the most ill-conceived villain ever rather than doing more with Tasha.
So just because Janeway could potentially be brought back doesn't mean she will be. It just means she's a fictional character who died in an SF universe -- every such character has the potential to be resurrected.
