Yes, we are planning a release of EntLib for VS2008, consisting of fixes and minor improvements. No new application blocks though. So it will be more like 3.5 not 4.
Suggestions are still accepted (contact me directly or post your wishlist here).
We are also planning on releasing updated Hands On Labs with guidance on VAB and PIAB.
I encourage everyone with an interest in the future evolution of Enterprise Library to take up Grigori's invitation and post your wishlist on the forum. I'll be doing so myself - but I thought it would be interesting to see what everyone else comes up with before I declare my hand!
