As far as I'm concerned there shouldn't be more current gen stuff in comparison to past generations.
I doubt that would ever happen. Like you said, just by achieving the goal of having just about every game system known to man at the show, we're going to end up having more retro stuff there than current generation. That said, there's also little doubt that current generation stuff does very well. Our long-running Halo networks, for example, have been extremely popular over the years with each new Halo.
I'm not sure how many of you caught my interview on the Retro League podcast, but what I said there is how I've felt since the first day I signed on to work on the show over a decade ago and I believe it is the feelings of the majority of the group. We don't want the show to be pigeonholed as JUST a retro show, JUST an arcade show, or even JUST a vendor's market. We've been just a bit lax on the modern stuff lately and I think we'll do some more next year. I doubt it comes at the expense of anything someone here would miss, and it certainly won't have any bearing on something like a DHG room or E2M room (i.e., the two big rooms in the playable museum area.)
Now, I really don't want to say any more than that because I'm touching on things that we're not even sure about how it will turn out just yet. I think what changes are made, however, probably won't even register with many retro fans but should be a welcome change for folks seeking something new.
Later.
