Buy the NP mag when it comes out on shelves next week.
Some things I can confirm from the article.
-Developed by 5TH Cell.
-DS Only.
-Out this Fall.
-Yes, D-pad controls for Maxwell are in along with significantly improved stylus controls and camera is now fixed.
-Big updates to physics (it's still DS, but it's vastly improved).
-Levels are revamped completely improved (no more solving every level with rope/unicorn/death/etc), levels are deeper in content.
-The 10,000 words refers to adjectives, we didn't add 10,000 new objects, we put in 10,000 new adjectives (we put in some new words too).
-You can string adjectives together.
There's a lot more info in the NP article, buy it!
