But neither of your points lends itself to reasoning why Sony/MS would look to shorten console lifespan, especially when those re-released models are priced to produce a net profit and delay any investment into the next generation and increase the period of time those consoles are actually profitable without the consideration of attachment rates.

I think general consensus seems to be that this generation has been too long. I think the next one will be 4-5 years tops.
