Webi or BW 7.0?

Hello,

After I have read the roadmap and many of the forum threads, it still not clear to me, Should I recommend new projects to develop their queries with WAD 7.0 or should they use WEBI? Should we start to migrate our old WAD 3.x reports to WEBI? I know that when PIONEER will be released there will be a migration tool from BEX queries but what will be the future for the WEBI reports which connected through Universe from the BW? After building a universe and connected the Bex Query to the universe i noticed we have to build the report again in WEBI. I'm sure it wont be the case with Pioneer.

Please Advice,

David
