Some stuff from an interview from some magazine called Great Mechanic DX7 via 2ch:

According to Great Mechanic DX7:

1) Talk between Chiba and Teraoka

 - If the capabilities of the Gundams from four years ago was 100, then their successors, aside from the 00, are 150 and the Ahead is about 140.
 - Because the entire world under surveillance by an observation satellite, Ptolemy had to shift about underwater. When they went out into the sky the top-side was disguised with optical camouflage. 
 - Kuroda likes gimicks. In the second season, a lot of them came out quickly.
 - The A-LAWS are an elite force. They don’t have more than 100 GN-Xs and Aheads all together. 
 - 90% of the world is peaceful. We’ve been focusing on the middle east, but in other areas there is no conflict. 

2) The Federation’s public relations policy

The world of the second season is a super-regulated society because the Federation government strictly controls thoughts and information, even though people are living it’s become a very narrow world. Why doesn’t CB blame such an awful group while saying that the A-LAWS are evil over and over? That’s because acting on a personal grudge is useless.

グレートメカニックDX７にて 
①千葉と寺岡の対談 

・4年前のガンダムの能力を100としたら、00を除く後継機は150、アヘッドが140くらい 
・世界は今や監視衛星で全域をチェックしてるためトレミーは海中を移動してる。空中に出るときは上面を光学迷彩 
・黒田はギミック好き。二期は早めにいろいろ出す 
・アロウズは精鋭部隊。ジンクスとアヘッドはあわせて100機ほどしかない 
・世界は9割がた平和。中東がクローズアップされてるが、他の地域の紛争はなくなってる 

②連邦の各方面に対しての政策 
二期の世界は超管理社会で 連邦政府によって思想統制 情報統制が厳しくおこなわれており生きていくのに 窮屈な世界のようだ。なぜこういう悪い部分をCBの連中は糾弾せず、アロウズが悪いという主張を繰り返すのか？あれでは私怨で行動してると言われても仕方ない。
