Not the same at all. The previous housing bubble was a result of widespread fraud by the banks. Now, people know very well to look out for that exact thing happening, and it isn't.

If there is a bubble right now, which there probably is, it is a speculative bubble. People believe that housing will forever quickly grow in price, so they are willing to pay above reasonable price to not miss out on the opportunity. Which in turn increases the prices further. It's a self-sustaining cycle, but at some point there won't be enough capital to sustain it any longer. Can happen in a year, can happen in a decade, can happen tomorrow.
