I can only speak for myself, but I look at that as them being typical shifty politicians, wanting to have their cake and eat it too. A review doesn't preclude their initial promise of no new stadiums, and I haven't heard them actually disavow that. But we'll see what happens.The LNP did say no new stadium initially.
They covered themselves with the 100-day review later, so i don't think it will be a problem for them promises wise.
