They just keep saying things like "very soon". I chat to Gavin (the programmer) on MSN and he's adamant he's not releasing the game with any bugs at all. I think they want it fairly polished by the time it's downloadable, the beta will effectively be the finished game, just with less races etc.
A few key points;
*The game will be released with the Feeration only as a playable race, other races will be created later. As the whole point of the game is moddability, there will be a race creation program (basically, put race picture here, choose morale implications etc). A stoned monkey could create a new playable race and new ships will be downloaable all the time. So you can play as the Tholians if you want, or anyone else you or the official makers create.
*The concept of "range" has finally been scrapped. Each ship will have a fuel reserve and will need to refuel at starbases or shipyards. That means you can now enter a wormhole and explore space on the other side.
*The ridiculous "autoupgrades" no longer exist. When a new class has an upgrade available, you'll have to get individual ships back to shipyards for refit. This will be a challenge during times of hostility, (should I leave the border undefended for 10 turns while I refit, or leave an obsolete ship defending?)
*The smallest galactic map will be 4 times the size of the largest BoTF map, I shit you not.
*When you sign a non agression treaty, you'll still be able to enter another race's space, they'll be pissed if you get cought though.
*Build times will be far more realistic, maybe 10-20 turns for something like a Galaxy class, Starbases could take 40 or more overall.
*Ships will serve the functions they serve in the show. A Galaxy class will be faster than anything in the fleet when it's launched, it will also be powerful and have magnificent scientific abilities. It's cost will limit production in favour of smaller, more specialised ships, (eg Intrepid for scouting, Nova for scanning anomolies, Defiant for fighting etc).
Well they're a few of the bits I'm looking forward to, I honestly think we'll be playing it by Sept/Oct.
