I reckon it could happen during the summer if there isn't any big releases announced before then. Even better do you think we could get to a point where total hardware sales are lower than 50K?(including 3DS)
By Famitsu we got to 62K last year (I picked an arbitrary week and started checking around, it could have went lower): http://www.neogaf.com/forum/showthread.php?t=844085
To hit this scenario, we'd basically need the 3DS at 20K (which would be about 5K below last year), the Vita and PS4 to be approximately 10K each, and for the Wii U and PS3 to average 10K combined.
I don't think it's off the table, but it will likely be close regardless.
