I think you're probably right... It's definitely the Park Stop video that forced their hand in going public at this stage.I'm totally convinced that this was supposed to be announced some time next year after whatever timeframe they meant by 'many months', but enthusiast sleuthing forced their hand a little.
But I also think that they're much further ahead than they're letting on, and have actually managed to keep this under wraps for a long time already. The concept art of the potential junction 14 site is said to be at least 11 months old. And you don't just spend 10's of millions on land for a project like this without having already consulted local authorities.
