Maybe 2015-2016.
3DS should pull no less than 3mil next year and tbh i dont kno if vita could make 3mil. This year it had a major price cut, 2 new SKU (Vita 2000+Vita TV) which only Vita 2000 is doing okay now, GE2, and some big IPs.
I think it'll definitely go up YoY but your 4.5mil? It'll need to pull 3DS #s for that. Vita this holiday might be wayyyyy up from last years but its nothing big (especially when you consider it just got its huge game and Vita TV last month)
2.28mil is the lifetime total with 3 holidays (still another 2 weeks to add of course)
2011= Around 450k (only 3 weeks of sales)
2012= Around 700k
2013= 1.13mil
I dont think it'll triple its lifetime time next year.
FYI, MH isnt going to be big. Thats that bad title WiiU+PS3 got (which did terrible)
Edit: PS4 launches and people will be spending money on that which means less potential sales for all handhrlds+WiiU.
Also 3DS has some big titles already coming out next year (nothing like MH/pokemon) as well as WiiU (MK+SSB+LoZ Dynasty Warriors)
