Why would you not release Expansion kits for SD3 at the same time as you do for EZ Drummer 2?
Referring to the new UK Pop expansion.
I have invested a considerable amount of money in Toontrack including EZ Drummer line for years... and recently upgraded to SD3...
I don't want to invest in new products for EZ Drummer (regardless of the ability to use them in SD3) only to find that the same product will have a SD3 version come out 6 months from now!
You should at least publish as to whether or not an SD3 version will be released at a later date.
Your customer base is loyal and shouldn't have to purchase redundant expansions.
