Same as most on here.
I can't see that much point in the ODAC+O2 combo if there's a an ODAC+ODA around the corner. I mean, both are in effect desktop amp/dac combos, around a similar price point, but the latter is way more convenient as it'll have rca's and most importantly a 1/4 inch jack. Most likely it'll sound better too, although i'm not sure how much low impedance cans/iem's will benefit from the bigger amp.
Out of interest, do you know roughly how big the odac+oda will be dimension wise. I'm hoping it's not more than 3/4 times the size of the o2. Probably start building these in july or something, you reckon?
I'll definitly order an odac oda combo when it comes out!!
