i got the trial this morning and played around with it for a couple of minutes.
The sweep mod (i think that should've been called 'sweet' mod. )

is really great, it makes the lofting tool look very outdated and hopefully they'll throw it out eventually. This little sucker is gonna save me so much time doing architectural stuff (wich i do alot!)
The hair and fur is nice, havn't got a chanche to test it extensivly. I was kinda dissapointed by the rendertimes when using hair and fur i think maya is faster.
i hope i can find some time to explore the new features a little better
