^I think it will because in the future Newark will have far more developments chained together which lends itself to a larger, more complete downtown. Before the Pru and Hahnes renovation all you had was an enormous wall of concrete and a huge parking lot, each taking up nearly an entire city block. Now that they're done (and mostly there) you have a damned decent street wall that stitches well with the park across the street.
Take this link for example (from njbiz):
Apparently they're making plans to turn an old building into loft-like office space. The property sits at 277 Halsey St, which is right in the shadow of the Teacher's Village neighborhood.
Now, whether or not there would've been interest in that property if Teacher's Village wasn't built is anyone's guess. But I'd surmise that there wouldn't have been ANY interest without Teacher's Village simply because the area was completely desolate before it.
