Math is hard. Math, when you are shy on coffee, and forget a kickstarter, is worse.
My rough count as to what is coming in the next few months is:
Rivet Wars (forgot this one yesterday) - 160 models, more or less. Supposedly still on track for September, IIRC, but I am assuming October.
Relic Knights - 58, I think. Seems like it should have been more, but I think that may be it. Fortunately, I won't see this until the holiday season, so I might have until Dec to clear some space for them.
Robotech Tactics - won't see this until January anyway, no matter what they say. 100 models, more or less, depending on how I fill out my pledge manager in the next week or two.
Wild West Exodus - 45 or 46 models, I think. The pledge manager was done as an .xls file, so I have my copy tucked away somewhere, but I think I pretty much know what my share of it is looking at the KS page. Those are due in Sept/Oct, and are still on track.
GenCon - not attending, but PP and Wyrd both let you order con figures online, so I'll probably be adding 20-30 models from those lines later this week.
So, 400 models, as a ballpark, back of the envelope calculation. Add in a special order or two, and some trades (if I get the terms nailed down), and there is an even odds chance that I will add another 5-600 models between now and the end of January. Just extra incentive to get painting, I guess.
ETA - so far today, I have put paint (to a greater or lesser degree) on 13 models. Not as nice as yesterday, where I managed more than 25, but better than 0. I hope to paint for another hour or so tonight, and a similar amount of time tomorrow.
