Ok, here is the exact words from the Greek Metal Hammer:
[...]As we were on the road, Anders Johansson dropped the second bomb: his brother, the keyboardist of the broken up Stratovarius, Jens Johansson, these days, is at New York, where he's recording with Tolkki/Kotipelto/Kainulainen the new album of Stratovarius![...]
In my opinion, Anders (no matter how "crazy" he seems to be) is a professional musician and a reasonable person. He couldn't have lied. Since he said that this must be true (except he lied but I don't believe so). Now, there are many "whys' about the place. There can be many reasons that we are not able to know and some we can only imagine

Some of them would be that thing with the explosions someone mentioned. Another one would be that they don't want to let news go out yet cause maybe nothing is sure. Or they might want to work silently away from all that interest of the fans. Or for contract reasons...or...or...
Those reasons are only what I have to my mind (my imagination in other words) so I may be completely mistaken.
But what's for sure (in my opinion) is that what Anders said is true.
