The questions in my mind are
 - how likely is that E-On will be bought?
 - and by whom?

Over the last two versions of Vue, there's no doubt E-On targeted the professional market. IMO It's highly likely they're making themselves more attractive to possible buyers.

Given AutoDesk's current acquisitive mood, E-On are a prime target as Vue's feature set complements AutoDesk's current portfolio: AutoCAD the CAD software, three top 3D apps 3DS, Maya and XSi and other complementary software. Most noticeably in the last category is Stitcher, acquired during the taken over of RealViz, a French company, in May 2008.

Irrespective of the above, E-On have a lot to deliver with Vue 7. Especially given the increased pricing.

Cheers,
Mark
