I've never bought a console at launch and so far it has served me well. I got my WiiU Wind Waker bundle in 2013 when sales were horrible and retailers were doing their own unofficial pricecuts for 200€ in a sale.
I got my 3ds XL about half a year after it released, though. That was probably the closest to a 'launch' I ever got something (not sure if a new Sku counts in this context...).
Now, I would have gotten the Ps4 at launch if it had been backwards compatible. I entered 7th gen so late that by the time I was in the market for the Ps3 the Ps4 was already announced and if they had magically achieved native backwards compatibility I'd have skipped the Ps3 and went straight for the Ps4.
Right now I'm waiting for more games that really interest me before I jump on it.
