Alright i am compelled to make an official post regarding this so all customers dont have to PM me indivisually and ask about this.
I have started vB4 journey into Styling and Designing, with MorbidBlue alreay released. Next up for release is going to big release. Blackstream 2.0 in 2 version [Midnight and Dawn]. Whats with the fancy names you ask?? Well its not codename or anything of sorts but 2 versions one would be darker and other would be lighter, use your IQ to wonder which one is what.

Both would be separate releases, this time both will have 5 Background Sets included in them and even the fluid option. So the pack would be :

Blackstream Style [midnight or dawn]
Fixed and Fluid.
PSD and Resources
5 Backgrounds included.

I want to clear another thing before i get your hopes up. vB4 template structure is different, styling is much extensive and i always like to give clean,professional and unique designs. None of vB3 style will get an upgrade because the structure is too different. I have to redo all styles and improve on it. So those who think its just a PORT from vB3 -> vB4. YOU ARE WRONG.
Just look at morbid for vb3 and vb4.

The point of above monologue being vB3 customers will NOT get a free update for vB4. But they have a 50% off on vB4 Styles. I hope you under the effort that goes into doing these styles and if it was a simple port i would have given a free upgrade but its NOT.

Another thing, Initially my styles will NOT include CMS or BLOG support because i dont have it yet, but rest assured all styles released under vB4 will eventually support the suite. So if you own a vB4 License which only has Forum Style, once i upgrade them to CMS and BLOG you will get a free upgrade (see im not so evil).

Thats it! folks thanks for tuning in, hope i have cleared some lingering doubts.Thanks for your support and any question you might have, you know im always around to shoot em down.

Cheerios!!
