This post is kind of pointless as the OP has made his mind up. But while he waits for his board to arrive I'll give my point of view as it may make his wait a little more enjoyable.
I own the HHKB pro 2 and think its great for gaming. Firstly the placement of the control did feel a little weird. For the first 10 mins I thought I wasn't going to be able to get use to it. But after around 15 mins it seemed OK. I then kept taking frequent breaks and small play sessions until after around 2-3 hours of practice it was exactly the same for FPS games then the regular.
I am good at adjusting to changes like this though. My friend said it would be impossible for me to switch to using normal Y axis after playing inverted for 18 years. I switched 2 weeks ago (for the LOLZ) and it took around 24 hours of game play. It also caused me to feel ill while not playing games LOL point is, if you can switch that then anyone can adjust to a key in a different location with very little gameplay.
However I also own a KBC poker with reds and while I game fine on both I feel the poker is the better choice. Basically I love them both the same, but one cost 3x more then the other and isnt 3x better. Just different. The HHKB is more refined but the poker with reds has its own charm.
Right now I use the HHKB for typing and the KBC for FPS games. The feel of reds while gaming is just lovely and feels so natural.
The major benefit to me with the size of these boards is not the portability. But the form factor. They are so small that it perfectly matches my FPS sens of 30-40cm/360 it means I can have all that mousing space and my keyboard centred nicely.
You made the right choice IMO going for the poker and another +1 for the reds. Enjoy that cute little board.
If I had to get rid of one of mine it would be the HHKB. Purely because its worth more and I like them both the same. And the KBC is also great for typing on.
