Sorry Chris, the problem with local news articles is that don't archive all articles.
The "source" from Wikipedia, for example is now dead.
However, I can categorically state that it was reported that Shrub Hill would close.
Think about it - there is very little place for Shrub Hill as it is; it only exists due to the track layout restricting use of Foregate Street.
To be honest, re-doing the track layout and signalling would be a better use of the money!
There is, however, a massive plan that will redevelop the area to the east of the station which could mean that it is economically viable to keep SH. Caveat: I have no idea the current state of the plan - this link is from a couple of years back:
