According to Nowgamer, Ubisoft has confirmed the Splinter Cell HD Trilogy is happening, but has made no mention of an Xbox 360 release.

The fact that Xbox 360 has not been mentioned is a curious development.  After all, Splinter Cell debuted on Microsoft’s original Xbox, but at the same time a 360 version has not yet been denied.

It is assumed the trilogy will contain  Splinter Cell, Pandora Tomorrow and Chaos Theory.

No additional information is available and we will let you know when it is.
