Will we ever get a release date, and what is with the new and very stupid weapon system? I mean why make it like that?
NO! You will never get a release date!!! MUWAHAHAHAHA!!!!!!!!
I kid.
Of course you'll get a release date eventually. Duh!
As far as the weapons system, it's hard to fully explain to you why it's awesome until you actually try this out for yourself. Wait until you have a character that's custom made to your liking, weapons and all... In short though, it's a rewards system, and helps generate uniqueness in the game. If everyone ran around as the same, well, that's been done before. This isn't about just making a bland character. This is about showing off the character YOU made, and YOU worked hard to customize. You'll be rewarded with things to customize as you progress in the campaign in online modes.
This might be hard to understand at the moment, and it may not make sense to you. But I ask that you be patient, and try it out for how amazing it makes the game once you get your hands on it.
Will VS's suck up T-ENG in multiplayer?
Yep. There's videos online of the multiplayer battles that were on the show floor of TGS. I suggest watching them. You'll love the VS action. 
Snow, as you have confirmed that players will still have the ability to be invincible during certain animations, what are the developers doing to teach new players how to take advantage of this feature?
Personally i think theses kind of features shouldn't be in a game like this and i'm hoping that Capcom learn how to improve their animations so it doesn't make the game feel unrealistic.
I take it you're not a Street Fighter player... SF is very similar to LP in this sense.
What makes Lost Planet shine among other shooters is the fact that it has a layer of strategy most games don't. Take for instance if someone starts shooting you before you have time to think. Most games that means your dead, wait to respawn to start shooting him before he shoots you. Now take for instance the roll. There's no regenerating health, so this adds a section of skill based gameplay as a factor. If someone starts shooting you, you usually have time to counteract this. Turn the tide.
I could go on and on if you're interested in my rants. But essentially, those animations make Lost Planet what it is: a game about skill. Not about who can pull the trigger first.
That said, many of the old animations are gone, have been sped up to improve gameplay, and some are no longer invulnerable.
