Embarcadero buys KSdev to work on "next generation frameworks". This is announced in ksdev home page at http://www.ksdev.com/. Actual wording (in case the site goes down in the future):

While at Embarcadero we are not bringing VGScene, DXScene, or ImageFX code forward. I am working on a very exciting next generation App Development project that will go beyond what the KSDev products were providing. It is safe to say that similar functionality of these frameworks will be made available in future Embarcadero development products. I believe it will be well worth the wait.

If you are interested in being a part of the field tests of Embarcadero's "next generation frameworks" when they start to become available...

So I have to agree with the comments from Chris Rolliston of Delphi Heaven at http://delphihaven.wordpress.com/2011/02/06/embarcadero-purchase-ksdev/ who ties the announcement with the words of Allen Bauer about " the revived cross platform efforts". Quite interesting, I have to say.

I guess only time will tell what's really behind this, but the fact Embarcadero is buying small companies with great technologies "around Delphi", is very positive for the product. This is how Allen put it on Twitter:
