It would seem that way, yes.
But really it's just that we all expected anime from the start. The live-action coming first led a lot of people to believe that when we got anime, it should be something really exciting to make up for the live-action announcements. In a way FUNimation should have expected this backlash, as in looking at it that way they totally brought it upon themselves.
(not forgetting to mention that the FLCL announcement came between, making people want something even more exciting.)
Most would say that these two anime announcements were at least a little acceptable, just more for if all of the announcements had been anime and these had been the first ones to be announced. There still would have been a lot of complaining, of course... But it would slide very easily within the remaining days of the roll out when more exciting anime was announced.
Now a lot of people are going to complain no matter what tomorrow. Honestly I don't personally see it being anything that will blow us out of the water. It's obvious FUNimation just didn't have much to announce for this.
And if you want to know why people expected this to be all anime, and why people should at least try to understand where we're coming from - It's because first of all as I mentioned earlier we all know FUNimation for the anime, and second of all, probably what made everybody thing this would be all anime even more - Last year's event around this time was EXCLUSIVELY anime, and I'd be willing to bet that if there was a similar event the year before it was also all anime.
It doesn't matter whether FUNimation said it would be all anime or not, it was logical to conclude that it would be all anime given the past. And come on, we all know that these live-action announcements were just filler because they don't have much to show. It's fine that they don't have much to show, there's a lot of complications in licensing series, I know... but they shouldn't have acted like they did.
