v2.6 is only Linq and a few breaking changes. We want to keep off any other feature requests to avoid delaying Linq support due to these feature changes. So v2.6 won't have many (not much actually) new features besides linq (and the stuff required to run linq, like anonymous type projectors, derived table support.. ).
The #of lines is rather small, I'll add it to the list but even though it's small, it is likely being postponed till v3 due to the reason above
(edit) actually it was already in the tracker and scheduled for v3.
