That's one of the actual purposes of retailers/distributors.
That's why companies sponsor events and have sponsored individuals in attendance.
I get your frustration, but its 2020. Obviously the Hide is the best one-stop shop for info about upcoming and current products. If you keep up with following the content here and listen to Frank's podcast, there's always discussion about upcoming products/designs. Hell, a lot of the manufacturers out there have accounts on here and frequently communicate directly to us filthy commoners. You cant ask for a better or easier way to go about it.
You can keep up to date with products and communicate directly with companies all from your phone while sitting on the shitter. No need to take time off work, fly to some random place, pay for a hotel/meals/car, waddle about for a day or two, then travel home. Companies incur those expenses, and more, each time they go to such events. Personally, I don't want to have to pay a higher product price in order for manufacturers to compensate for the increased expenses for hosting a consumer-targeted convention each year.
Social Media, as much as I fucking hate it, is the best way to not only find out about what each company releases, but also allows for a direct line of communication between the consumer and manufacturer. Instagram is free and seems to be the fastest way to follow and keep up with each brand/organization out there. Use the available (and free) instant means of communication to send your questions to the company's Sales/CS team.
Also, having worked customer service, I wouldn't want to put that kind of strain on the sales/marketing department (not to mention the backlog) where they are trapped in a giant smelly hot convention center talking to someone who just wants to talk and isn't going to be using or purchasing the product anyways. It's like the poor souls that work gun shop counters in stores. It's an 8 hour day of dudes coming in to talk about what they already own or how they are just looking but want to finger fuck everything in the case knowing that they aren't going to buy it. Shit you can find a stack of youtube videos of dudes who, somehow, got into SHOT and fumble through an "interview" with zero prep or even the most basic of interpersonal or interviewing skills. That's the last thing we need adding to the cluster that is "reviews/highlight" videos on YT.
