There will likely be an Invitational this year. The idea is on the radar.
On our radar too looking ahead, 6th Edition has been out for nearly a year, and BG has yet to run a true 2000 point event. Initially, there was caution and concern with easing the community into 6th, coupled with very valid time concerns in parsing out rules in real-time. What I see now is a community that can handle those elements. I feel players have had reasonable time to consider and build their armies under this concept... and if not at this moment, then very definitely whenever this goes down.
That said, I would not expect 2000 points to ever be the "norm".
What's important to note is that not every BG event is geared toward being as competitive as possible. For now, that's for the GTs to concern themselves with. Sometimes, the BG aim is for something a bit more fun/ridiculous. That BG happens to attract an amazingly competitive crowd is just another phenomenon entirely. I chalk it up to Sam's sexed-up judging.
