Well they're not Intel or even Apple. Keyboard manufacturers aren't known for giving roadmaps. Ask Das about the Das4.
Let's review new products in 2009 in the Mechanical Keyboard biz:
Topre 87U (anyone remember the difference again between the 86U?? - oh yeah,it's black and has the RED ESC key !)
Topre $150 numpad (aimed at banks)
DSI Mac Modular in Black (white one was available earlier)
Deck Tactile in clear cherries, only one LED color and no mini
iRocks 6230

..........everything else was available earlier although EliteKeyboards sure made it easier to get. I didn't count the purple WASD keys as a new product.
We'll see if Unicomp has the capital to do new products.
To piggy-back on this:
The 87U also had indicator lights integrated on the Lock keys, but yeah, it was basically the same 'board as the 86U. Not a whole lot of innovation there. There was also a 55g version of this 'board, but again, that's just a part swap.
The DSI modular (even in black and a Windows version) was announced last year. It took a very long time for it to reach the market.
The Tactile Deck is just a parts swap. Yeah, I guess it's new product, but really, it's just a regular, production Deck and someone threw some clear switches in the hopper.
The i-Rocks KR-6230 was announced (and I believe, released) last year in Asia markets, but it just made it to US recently.
In actuality, I don't think any quality keyboard manufacturer really does a whole lot of truly "new" products. In the case of Cherry-based 'boards, all manufacturers do in many cases is just drop some different switches in the manufacturing equipment and, voila, a new keyboard. Really, other than i-Rocks and DSI, it has been quite some time since a quality keyboard manufacturer has put out a completely redesigned product.
I don't think Unicomp is alone in their apathy towards making truly new products, but there are several factors worth considering:
-If it ain't broke don't fix it. Why screw with a perfectly good design if your customers like it?
-Can the market really support your 50 different models?
-How much do you stand to lose if your product flops?
All of these questions are pretty much related, but think about it. These keyboards aren't cheap to manufacture. At least for MS, Logitech, Kensington, et. al., they're making rubber dome 'boards with parts that can be used in several different models. They are mass produced and cheap to make, so they don't have as much to lose if they have a desgin that flops. With Topre, Diatec, et. al., their market is much smaller, their product more expensive, and their market much smaller. Every model they put out has to, basically, be a hit. I think that's why you don't see a whole lot of innovation and new products in the quality keyboard market. Once these manufacturers "perfect" a design, they are going to stick with it and maybe only change the color, switch type or where the status lights are. Now, Unicomp might be a little less bold than these other companies, but in this economy, and in the market they serve, it is somewhat understandable.
