Read the Smith and Tinker interview (link is at the beginning of this topic). I'm really impressed they decided to go this route and let the fans know so much so soon. I think you are also right Skyfaller... lets hope this puts some serious pressure on the publishers.
"Russ Bullock: We feel confident obviously in the PC and its control scheme that can be realized because it's been done before. But for the Xbox 360, we've spent a lot of thought and a lot of time in playing around with the controller and finding ways to give the same level of control in the way that you throttle, in the way that you turn and move, use your jump jets, and everything that gives you that MechWarrior experience that doesn't turn it into a power-up pickup sort of arcade style game. So that is something that we're spending a lot of time on – all the answers aren't there yet, but we want to make a MechWarrior experience and we feel like we can do it both on the 360 and the PC.
IGN: Right, so there was definitely no discussion to having a more arcade-like feel for the console? There was always a decision to keep it as a balance of action and simulation for both platforms?
Jordan Weisman: Yeah, I think that MechWarrior was kind of the PC's first big action title, and even if you go back to MechWarrior 2, it certainly had sim aspects, but the sim component wasn't so overwhelming that it became inaccessible. We want to walk that line as well, that it's an action sim as you said, not a sim with action."
...really, that is all i needed to hear
As far as concerns of accessibility and mainstreaming the game it sounds like the developers are trying to work to flesh out many aspects of the mechwarrior series that haven't been touched on. When they say "reboot" they seem to be stressing more of a "let's start the story from chapter 1". Lets face it... mechwarrior really never did that to begin with as the game most of us first played was either mech2, mech3, or mech4; pretty much all of which are (or pretty much) post-3050. To be fair, it still isn't really the "beginning" of the story, but definitely in the beginning of what most of us are familiar with: the height of the Succession Wars.
Honestly, i would be cool with a "Fall of the Star League" storyline culminating in Kerensky's Exile... and maybe a nice little fan service ending with the creation of the Blue Star Irregulars... that would be a bitchin' storyline.
Look it up:

They also seem to be taking a similar position in character development to that of Mech4 Vengeance. While i wasn't thrilled by mech4s story, I'm hoping they bring something more dynamic to the table... some form of nonlinear storyline would be welcomed, but it needs to be more than simply 3 different rather boring endings.
One thing I am REALLY loving that they mentioned is 4 player CO-OP through the main campaign! YOWZAH! Now we are talking. A lot of people are freaking out with all the Gears of War and Call of Duty references in their interview but I see it more as comparisons of great multiplayer experiences than "another mechassault clone". It is my understanding this game is to be developed for the PC and will be PORTED to the xbox... not the other way around. I think they have user content in mind.
They also specifically stated they want to introduce a sort of RPG element of earning skills in a specific mech class and making every mech from 20 tons to 100 tons viable in combat as a result. I think this is a great idea although if I get schooled in my heavy mech by a Locust i am going to be pissed.

Thankfully, they don't seem interested in introducing any non-canon weaponry or mechs, but they are bringing back the circa-3025 "unseen" mechs borrowed from Robotech. It is my own personal hope to finally be able to pilot my customized Shadow Hawk, Archer , and Battlemaster --->:geek:<---
A conquest mode has already been hinted at for multiplayer. Who knows what they have in store, but it definitely appears these guys are all fans of the original source material and we can safely expect more loving care than what M$ gave it (i hated Mechassault since day 1 not because it was a really bad game, but it felt like MS had butchered the franchise).
Ok... I need to stop before I go critical.
Bottom line... IF WE WANT THIS GAME TO BE AWESOME, AS FANS OF THE SOURCE MATERIAL,
WE NEED TO GIVE THE DEVELOPERS OUR WRITTEN SUPPORT NOW WHILE IT STILL MATTERS:
