Well Nero's the new star around Devil May Cry. All newbies in the series like him more than they like Dante and find him also easier to use. So it's to be expected that he may become some kind of regular around the series.
However we shouldn't lose hope about Vergil either. Even facts like:
1)MANY people hope that Nero is Vergil in some way
2)Everyone was happy to see Yamato back
3)Almost every interview includes some part about Vergil
...and so many other things will easily make Capcom realize that Vergil SHOULD and MUST return at some point. (I really hope that point isn't Nero's Devil Trigger by the way)
After all the story is about Sparda and his descendants
And since Lady and Trish got to reappear...
(And by the way I hope there's a cut-scene with Vergil at the end of the game as a small prologue for his return)
