Yes, equal coverage is given to both the Sokolov variation as espoused by Vigus and the mainlines as played by Moro.

Well, I like the ones I have (Taimanov Sicilian, QGD, Nimzo, Meran and QID. Peter Wells and Reinaldo Vera are two very capable writers; James Rizzitano is no slouch either) but I haven't read them all cover to cover, although I went through most of the Meran one in particular and learnt plenty of chess.

The only one I didn't like was the one on the English - I much preferred it's Everyman counterpart in the Starting Out range (by Neil McDonald) although that opening is perhaps not best suited to such a book to begin with. 

In general, though, I think these Chess Explained titles are much better than the Everyman Starting Out offerings.
 
Also, although not strictly a Chess Explained title, although it seems it was originally conceived as one, Peter Wells' Caro Kann book is great, too, in a similar style but with added depth.  Partners well with this Slav book, naturally. 

I bought my copy yesterday. It's the kind of 'opening' book I have been waiting for all my chess life : one that tells you what middel game the opening leads to. (Are the other titles in the Chess Explained series as good ?)

Past books in this series have been worth the money, and Vigorito is a capable author.  I'll certainly buy it.

Well, reviewers certainly don't get their copy in advance of the author  

But seriously, I think it has only just come out here in England and so copies may not have been with reviewers very long, perhaps only a matter of days ago, if indeed review copies were sent out.  I bought it on the strength of Vigorito's last book on the Semi Slav, which although not really my opening choice was a very well researched and written book, in my opinion.  Well, I also bought it on the strength of the excerpt on the Gambit website, and because I wanted some more up to date coverage than my current sources on the Slav lines in the book.  (Those sources being mainly Sadler, Flear's Starting Out, Kasparov's MGP Vol 2 and some compendiums. I also have James Vigus excellent Slav repertoire book, but wanted to look at mainlines outside of that repertoire)

Fluffy - be careful you don't get asked to provide a full review. It could even harm sales of your Semi Slav book (which I also own, incidentally) if you persuade us to adopt the normal Slav instead.....

Well, it hasn't been out very long yet, to be fair.  My copy still hasn't arrived since 'entering the despatch process' of the online supplier I used. 

I hope it's good, though; my copy of Sadler's Slav book is hopelessly out of date, especially in the 6.Ne5 line, something I'm interested in.

Agreed.  This looks pretty good.  Maybe it'll help me finally make a decision between the Dutch and the Ne5 lines.
