Each day will see a new Indie bundle with about 5 titles each. Other bundles are publisher or series specific like before like the THQ Collection or Bioshock Franchise Pack.
While these details could of course change before the summer sale promotion arrives, it seems unlikely, but these remain unverified by Valve who has at least confirmed a summer sale.
Most titles or series during the summer sale period are discounted by a whopping 75% or so when they hit their allotted time in the spotlight, otherwise it’s usually around 50% off. Recently EA criticised Steam for these price slashings saying it devalued the developer’s work, except they then went and launched their own hefty sales on Origin.
