The no action points thing might not turn out to be terrible, depending on how they implement it. The perks system for soldiers, if done right, could play a nice role here so it doesn't feel dumbed down. As for the bases, whenever I played either UFO: Enemy Unknown or Terror from the Deep, I'd always have one main base where I'd keep the soldiers, do research, etc. Then I'd set up radar outposts with hangars for interceptors and cargo bays so I can move crap around, I never saw the need for more than one big base - so these news don't really worry me all that much. We can go into nerd rage all we want, these people are building a modern game they want to sell in a modern world. Even though I love the original UFO to bits, I find that expecting the game mechanics to stay untouched and identical to a 1994 game is totally unrealistic.
I'm not saying that they won't ruin it, mind you - but I am saying that we definitely do not have nearly enough information to tell just yet. So, fingers crossed it won't suck..
