Reaction to the news of the new edition has, as expected, ranged from reasoned to ridiculous (seen in particular on a general RPG forum you're all likely familiar with). I suppose that we all like to speculate and we all have our hopes for a new edition.
Personally, I just want to see the game treated well. Mongoose have not inspired confidence with many of their previous products, which are often good in spite of shocking editing, an obvious lack of playtesting and a rather poor content-to-price ratio... and of course there's the issue of failing to credit Steve Perrin in the new edition of RuneQuest. They have the resources and the experience to put out a really solid product, though, and to return Traveller, in whatever form, to being one of the best sci-fi games on the market.
I'm not really the market they are aiming at, of course, since I already own Traveller in the only edition I actually need and the problems I have with it have long ago been tinkered away, but I wish them well. Hopefully the setting won't be too tightly integrated into the game, which I think removes much of the enjoyment and wonder, and the mechanics will have the same level of simplicity and wide scope that the original had. It's too late to do anything beyond adding more fragmentation to Traveller - releasing a new edition is not going to make all the others go away - but for the many players who have never had the chance to play the game, or who have shied away from it because they didn't know where to start, this could be a golden opportunity to enjoy some superb gaming. Which is what it's all about, when you get down to it.
