Well there's a few changes incoming supposedly, the respawn system needs an overhaul (consider the case of killing someone on the edge of a respawn window - waiting 1 or 2 seconds can give them an extra 12 seconds respawn time), umm...
Here's a Brackhar-post with a bit more detail:

1) Continue the re-evaluation of the respawn system. We likely need a replacement to the window approach to get rid of some of the odd incentives it creates, but I'm unsure what the correct solution is that still hits the original goals the respawn windows were created to solve.
2) Spice up bot lane some more. My theory is that some small adjustments to how vision is given on the bottom lane may help make the area more palatable to non-standard strats, but talks are ongoing.
3) Add more caster items.
4) Generally try to improve the reinforcement in positive actions. This is an across the board goal that touches on a lot of things - kills, captures, quests, etc. - and extend from subtle UI improvements to larger scale system changes like the respawn rework in #1.
5) Continue to evaluate champion balance and be on watch for whether item solutions are sufficient.
Those are just my priorities though.
Keep in mind he's no longer working on dominion, that would be Geeves.
