1. Upcoming version
I have read on your twitter that there will be a new version. So, is there any date for the new version?
Which features brings the new version, upgrade easy to go?
Could be next week if all testing goes well. This isn't a feature release so it doesn't have any major new features, just the addition of auto Tweets and some smaller things. A new release was required to prepare the component to use Addons like the upcoming GeoMaps addon.
2. Comparsion jreviews vs sobi2
Which are the big differents between these products? Sure review is much more developed than the sobi2 integrated function. But what else?
I don't keep up with the progress of Sobi2 so you really should download and test both yourself. You can also do a search in this forum for Sobi2 because I have answered similar questions in the past.
3. Paid listing
If i want to choose this product, i also need a way to get the money back. I want to realise a review & directory website, therefore it would be great if my customers pays for this, monthly and anually. Also the listing should be set to inactive when no paying was done.
This functionality is not available.
4. Features
What current features does jreview has? Any chance to embed youtube videos on to a listing?
There are some others as google maps, etc.
Take a look at the demos site. You can do both youtube and google maps and it is explained in the tips & tricks board. There's also info in the new docs which are being updated daily
http://docs.reviewsforjoomla.com/5. Extensions, addons
Are there any addons and/or extensions? Right now i cant find some in the forum or did i missed a part? Would be great if there would be a section called addons where all addons/extensions are posted not like questions in tips and tricks, right now its hard to find any hack or something simillar.
The only Addon is the Everywhere Addon and there's a full description for it in the top menu on this site under JReviews. You can use most Joomla content plugins with JReviews.
6. Why didnt i found you earlier

Could be you didn't do a Google searc for: joomla reviews
