I'm willing to bet there will be. I'm also willing to bet half the stuff in it will be useless after the first patch. But they always have some nice artwork and stuff in them so if that's your thing, seems a safe bet it'll be available.
there's a strategy guide for every fighting game. if they have a fighting guide for tekken (because it's really not needed) then they will have one for SC5 and plus Namco has the money to make it and they want to the money from the people (like myself) that are going to buy it.
EVERY fighting game guide should look to the MVC3 guide. That is easily the best written guide ever. I really disliked the SC4 one as it was pretty useless and offered no real info for any level of player.
