Yup. Visually it's harder to tell, but once you get your hands on it, you'll know. JC covers a fair share of info in that interview as well in regards to some new bits to the series.
But yeah, full disclosure, I am one of the designers at Sumo Digital working on LBP3 and have worked on LBP Vita and LBP2 Cross Controller, too. Jaeyden's already popped his head in here as well and he's on the project as well (I'm sure hodgy100 as well). We'll definitely be showing off loads more in the near future which will answer a lot of your questions, so stay tuned. ^^
That is awesome. I have LBP1 and LBP Vita, but by far my biggest gripe with the games was the floaty controls. I'm definitely excited to see how you guys have changed it.
