Apologies for the second wall-ish thing of text. I accidentally went off on a tangent or two, but snipping stuff would break consistency.
I feel like you completely missed my very first point that was essentially that, at a Nintendo forum, bias will sway towards Nintendo as long as they present that one thing people were really hoping for, even if they know that if it wasn't coming during E3, it would be announced before the end of the year. For pretty much any year, that item can be Zelda. The in between years, it tends to be either Pokemon or the next major 3D Mario installment. It's the idea that, even though this forum has tried to be a little less Nintendo-centric by giving the spotlight to every company in some way shape or form, as well as getting reporters that don't only care about Nintendo news, it still suffers from the fact that its origins sit in having been a GBA ROM site (and with it being named GBAtemp and all), thus, attracting a primarily Nintendo oriented fan base over the years.
Now that isn't a bad thing, despite my use of the word "suffer", and I'm not complaining about that. Being primarily Nintendo oriented is what brought me and my DS loving, flash cart using self to this forum. I was looking for a place where I could both discuss the use of my flash cart, and discuss DS games in general. Lucky for all of us, the DS had a solid number of good titles that weren't all made or published by Nintendo, which allowed for it to branch out to other tastes and facilitate good discussion among everybody. The PSP being a homebrew machine helped facilitate even more good conversation about the merits of its homebrew. Basically, when I joined, the discussions were balanced, and although people were still at each others throats, it wasn't nearly as hostile as the forum as become. The newer hostility has been bred from the fact that the Wii U is basically just a Nintendo machine, and the 3DS isn't all that exciting yet, lacking more than one or two strong third party titles. They have turned back into being systems almost exclusively for Nintendo fans, destroying a lot of the cohesiveness that came with the systems of last gen, handheld and home console, that supported diverse tastes. Essentially, the console wars have flared back up badly, and Nintendo fans are heavy on the defensive, while other fans are heavy on the offensive. As silly as it might sound, many threads discussing upcoming Wii U games reflect this, and people will jump all over a Sony thread dare they release another HD collection (though I've mentioned the problems in the logic there in other places).
With that in mind, hopefully I've given enough of my thought process as to why I feel that, on a site such as this, a forum poll such as this is worthless in actually determining how good any of the presentations were. It still pretty much just comes down to "which company did you already like the most", which makes for predictable results. Even if you can personally say more interested you from all three conferences, and that you even watched all three conferences, many of the the lurkers don't and will never share your sentiments, as if it isn't Nintendo, it isn't for them, and that goes back to my first point of the fact that this forum is still heavily Nintendo-centric. As I said, in its current state, this generation of handhelds and home consoles hasn't been able to present one or two systems that support a diverse enough taste in either releases or homebrew to generate primarily healthy conversation when comparing consoles. The Wii U struggling certainly hasn't helped that, as even now, people are bound and determined to show just how well the Wii U will bounce back, even though its clear that the Wii U and Vita are probably doing about as well as they will ever do.
