I think developing sketchup in different directions might be interesting!
The fact that sketchup is still the 3D modeller of choice for many experienced modellers probably has more to do with all the great plugins around here than with the last upgrades we've seen.
The evolution of sketchup in the last years has been slow and not always successful (dynamic components anyone?)
My enthousiasm for this acquisition might have to do with Trimble's expertise in laserscanning as well. The holy grail of surveying in architecture would be an automated process from laserscan to a textured 3D model. If this would be possible with sketchup, I'ld be delighted!
So good luck guys, I hope you get all the freedom and support you need to take sketchup in new directions!
