He's talking about Sketchup Pro ;-) That's ~700 now.

I don't think anybody knows what the acquisition will bring for Thea. I have no clue about Altair, never heard of them, but I'm very wary about acquisitions in general.
In the end, only time will tell. But investors normally want to see their money back or have their own agenda regarding supported software - I saw that Altair has also bought Solid Thinking which was very crappy when I bought a license many years ago and is supposed to be better these days (I probably can't update anymore ... ;-) ).

Fingers crossed...

Cheers,

Tom
