Yes I think my convention was very similar to yours and I noticed the same points.
In particular the bethel brother emphasised that probably not all partakers at the memorial are genuine. So don't worry about the number, he said. (Are they going to stop publishing the number?) Then he said that "even if every single partaker is genuine" that still not all partakers count as part of the "overlapping generation". To be honest, to me he did not seem to say this with a great deal of conviction. It was a part of the talk he had to get through.
On the other hand he was much more confident delivering what I think is the strongest JW argument for living in the "last days". That's the observation that WW2 is pretty much the worst war humanity can ever expect to fight without ending civilisation itself. So therefore the end must come before a future war escalates into nuclear holocaust and the end of humanity.
Although he mentioned 607 a number of times, this seemed to be in relation to Habakkuk rather than tying it with 1914. I didn't really follow this point to be honest.
What I thought was totally weird was the way everyone uses tablets rather than Bibles. I use the Bible. Plus when they "released" the children's book but had no copies to hand out, was very disappointing.
I actually laughed out loud when the speaker said, "we are 103 years into the 'short period of time'". I honestly thought it was meant as a self-deprecating joke. Probably not, I thought I heard others laugh too, but maybe imagined it.
I met an "unbelieving husband" who recommended I watch "Cedars, JW survey" on YouTube. I pretended I didn't know what he was talking about! Sorry about that, if you're reading this. You know who I am now!
I met a few others who were enjoying the event to various degrees without necessarily believing it all. (Again you know who you are. I won't get too specific!)
And lots of friendly true believers too of course.
It was in general quite a friendly open atmosphere. The talks were not too hardline. In fact most were pretty enjoyable, like the one about the animals. And the drama was pretty good. The anti-gay bit was the only bit I didn't really like. Funny how they had a "Joe" character who was like Joey out of Friends.
As I say, to me the weirdest thing was the lack of book releases, and lack of Bibles, with everyone using tablets instead.
