Theres zero chance this game will be delayed this late in the day. Games only ever get delayed if there are serious issues (And even then...) not just because a bunch of us played a demo and didn't like it.
The hope will be that we are a small minority but i think they may find that the bad word of mouth and practically every previous fan cancelling pre orders may mean we probably are the majority.
Some changes to this game would be quick fixes in terms of dev time, such as adding shields to titans, changing their speed/player speed etc. But maps, they take time to make and play test and refine, let alone this all having to work in the single player.
I think the interviews are quite telling, it really looks like they used focus groups and research companies which is why they've gone in the direction they've gone in. To explain those a bit, focus groups are where generally an outside company hires a bunch of people (sometimes non games, sometimes gamers, sometimes fans, but generally gamers will be rather a loose term and you often find the quality of the focus groups are a poor representation eg. candy crush players are not gamers, they like candy crush and thats it) and get their feedback on the game.
It's all quite limited. Ask 100 people what they think of a game and you can easily get the wrong results compared to if you asked another group of 100 people.
The research companies are also hit and miss, some will be random people who made a company, others with some sort of backgrounds but not necessarily game design. They basically just give their feedback on what they like eg. the UI is too big, i was confused by the speed, i kept getting shot and didn't know why. The issue here again is most of these people are not gamers or good at games and are only briefly looking over the game without understanding it.
All the interviews point to this, saying players were confused by the speed (were they?) that they didn't know where they was being shot from (i think all would agree these new maps make it harder to know that) and the whole simplification for a game that really wasn't complicated all point to these sorts of groups and reviews changing the course of the game.
You see it in films too and it often results in either a bad product or a flat one. Sometimes these things can be good, its all too easy to become too involved in your game and they can point stuff out you either got used to or didn't realise but generally they just make a product bland rather than letting it be bold, different and standing out. Being proud of what it is and pushing for it, which is what the original TF was like.
The fact they changed so many things within a week to appease the fans is also telling as they know they've goofed up otherwise you'd stand by your convictions. It won't be delayed, it won't be a great game (sadly) and what will probably happen is they'll try to make it more like TF but without totally changing what is already there giving a half way house mish mash.
All of this.
