Nothing new IMO. Every 5 months or so, the hosts that seem to advertise the most here and @ WHT all disappear, go under, or get purchased by someone else. Hosting is basically three segments; small individuals running small hosts (like here - most of which will fail), huge host companies (hostgator, godaddy, etc. - these will stick around but offer horrible service and outrageous pricing), and the third category - hosts that are too stubborn to be different so instead stay stable, don't go anywhere, and usually are very fair priced.
Reference this post in one year, and you will see how few hosts fall into that third category
