I can shed a bit of light on what is going on.
This is a friendly buy-out and not a hostile takeover and it sounds like we will be just fine. Charley and friends are still in control of Steinberg and it's direction. They will operate as a arm of Pinnacle and Steiney products will be "Steinberg...a division of Pinnacle". Product names will be the same, although there was speculation that the cheapest Cubasis could possible be re-named but this was unconfirmed. The Steiny workforce is expected to be cut from approx 150 employees to 100, but most of the cuts would be in the administrative areas. All continued support and development of Steinberg products will continue as if they were never bought.
A couple of my thoughts from what I have read. I have heard both accolades and gripes about Pinnacle as a company, but one thing that everyone seems to agree on is that they have much better distribution and public visability that Steinberg had, so that will bode well for an increased userbase which in turn should lead to better development of SX which makes up approx 50% of the Steinberg userbase. With their marraige with Pinnacle we could see some exciting video features for those who are looking to do more serious scoring with SX. I think that the future looks good for us now that the smoke has cleared and we see where we stand. Of course only time will tell, but at least it is looking positive currently.
