Are you asking whether we think Creo is a threat to SW?
A threat no but a big concern when we can not convert files from one of our largest customers because of it.
I suggest voting on one of these ERs, or submit a new one:
SPR 625411: Add (Pro/ENGINEER) Connector support for Creo 1.0 (Creo Elements) in Enterprise PDM
SPR 647252: Support import of Creo 1.0 part and assemblies
SPR 656315: Ability to Import Pro-e Creo Parametric files
