I realise I'm a bit late to this discussion but thought I'd throw in my six-pence worth...

5 or 6 units aside sounds like quite a good game.

I don't mean this in a bad way...
It's been a while since I last looked at the Celtos rules and tho I could see the influence they didn't strike me as just Warhammer with D10s. They definitely needed a little streamlining from what I can remember and having units snaking around the place in base contact seemed a bit odd to me...like a conga if your going through terrain. I think it is a great shame that GW haven't spent the last 30 years actually refining and improving the rules of their games, to me at least they do seem to be rather bloated and ungainly.
Overall, I am intrigued to see what Brigade has in store but I think I prefer the idea of smaller games at what I'd class warband level; around 4-8 units aside with each unit having 5-10 minis for infantry, 3-6 minis for cavalry or maybe a monster.
I've had a some Fomorians and Gaels for a few years but as yet they haven't seen any paint. I'm VERY interested in Gaelic myth and have been researching the Invasion Cycle for a few years so its a shame I've not really felt inspired to paint them up. It does seem odd that Brigade haven't even updated the existing rules over the nearly 10 years they've had the game, a wasted opportunity perhaps. We'll se when (if) the new rules become available...
