Tempted to get Tier 3 for the Macharian Crusade omnibus, and The Rise of Nagash in T2 would clean up my tablet a little (own the print omnibus but damn it's heavy, the Time of Legends omnibuses for Sigmar, The Sundering and Nagash were large format).
It's a pretty good selection, although I wish they'd put the entire War of Vengeance trilogy into the bundle rather than just The Great Betrayal. The Buried Dagger is terribad, though. Getting localized versions into these bundles is a great thing to do, especially seeing how many fans Germany and France have as it is, and there isn't even opportunity cost for GW in this to begin with - if a reader is capable of fluent English, they'll read it in the original, but if they aren't, they wouldn't buy the bundle, and the other way around, people who don't speak German or French likely won't even download those copies. It's a super easy way to raise appeal and accessibility in a product type that's geared towards new or casual fans. Now, if their own webstore could do the same and just hand customers all language copies (while still keeping track of the primary language they wanted), a lot of unnecessary nonsense could be avoided, too. Especially when somebody buys localized copies, the trick is to get them into the primary language as easily as possible, and thus opening up more spending opportunities, if you ask me.
