The voting closed last month for the naming didnt it, and it was never due to be announced until just before the stadium opened, so Im sure they know the result and branding is underway/completed. Possibility also of course that the branding template was designed a long time ago and they just change the text.
Ive worked on a lot of construction projects over the years, and there is nothing in those pictures that would overly concern me in terms of progress.
Now, there may be truth in a delay, it could be all sorts of stuff that has lead to or caused it, but those images certainly aren't proof of it. Theres also little evidence of anything being 'ripped out', its simply all still at first fix.
