Microsoft has over 99,000 employees (this was as of end of business year 2013).
As a point of comparison, I have attached a picture from UA's holiday card this year - keep in mind, this includes not only code & app writers but an entire arm of the company which actually assembles real-life hardware like 1176's, LA-3A's & LA-2A's, 2-610's, etc. Lets not forget CS, staff in shipping and front desk/receptionist positions.
If you have read Gannon's posts here you know that between the Twin USB and Console 2 for FW, this has been a very unsettling, unexpected challenge for UA and they have made an effort to try and get in front of their issues with sporadic informational updates here at the UAD forum. I think, from the outset they thought both of these projects would be fairly smooth sailing. Instead, both have challenged UA in ways they most certainly did not expect and they now have found themselves in a less than ideal situation.
NAMM 2016 will be taking place in three weeks, based on Gannon's stated projected goals, UA will finally be able to confidently roll with the FW for Console 2 and the Twin USB.
so....three weeks..three more weeks.
