Can I Use Old Disney Infinity Characters In The New Game?

According to http://www.iheartinfinity.com/, the new Disney Infinity 2.0 comes with a few major upgrades, such as the new set of Avengers – Thor, Black Widow and Iron Man. Old characters have not been ditched either, so if you have a favorite, you can just stick to them. However, keep in mind that old figurines from the previous version are not compatible to the new ones, so you need to get these characters yourself. Other than that, the adventures they go through are also different, while the new updates and changes (such as the upgrade tree for new skills) applies to all of them.
