Hello Jony and TagBass,
Spark Vintage/Dubstep/EDM users will receive this week an e-mail with the info they need to upgrade to Spark 2.
Basically, you will have to log into your account and copy a coupon code to be used in the Arturia webstore. The upgrade price from Spark Vintage/Dubstep/EDM is 69$/€.
All the best,
