I would be shocked (no sarcasm) if a redesigned unit had anywhere near the number of hardware problems as even the current units.
Combined CPU/GPU on a smaller die process, reduction in chip set size, etc. will mean lower power requirements, lower heat, and higher reliability.
Plus MS has had more than just a few years to fine tune most of the kinks out of their manufacturing process (one would hope) as shown by higher levels of reliability with each subsequent redesign.
Claims like that are about as stupid as claims that a redesigned PS3 would cost the same (or more if you're really stupid) as the current models.
