Same question would go for Torchwood as well I guess, because we know Captain Jack will be appearing in Moffat's Dr Who.”
SJA is continuing, with RTD as the executive producer. He hasn't written for it since the pilot - but perhaps he might now.
Tennant only appeared in the most recent series, as a special treat for viewers once his departure was confirmed. It's unlikely he'd have appeared otherwise and also unlikely Matt would appear. It's not impossible, but it's harder to do crossovers when they are not part of the same production team and having co-ordinated story arcs.
The Doctor has never appeared on Torchwood, as it's an adult show.
We do not know that Jack will appear on Moffat's Doctor Who. It's pretty much confirmed he's not appearing in Series 5 anyway.
