Wow. Intamin? Launched? What about... B&M Hyper? Inversions?
Well they gave the source as a magazine, in which there aren't usually many rumours. Screamscape also cites an Intamin rumour, as well as a pic, staing that the space freed by demolishing Sierra Tonante, isn't what you'd normally build a hyper on.

(awww, it was a beautiful coaster)
Intamin has already built a 2009 coaster in Italy, at Terra dei Giganti nearby. For 2009, they also have planned a mega-lite, but otherwise, RCDB states that they haven't announced more projects
(

There are no launched coasters in Italy as of yet (well, technically there is one...). This one could draw crowds, as it would be the fastest coaster in Italy, and the 5th or 6th fastest in Europe.
ScreamScape also mentions the mystery DM track, but... Ohio? That's about 7.300 kms away from the park. While a DM absolutely would fit in the space, I don't think that's intended for Mirabilandia.
Well, that is what I have scraped together from this.
