I've seen evidence in the last few days of the pace hotting up.
1) Firefox now goes to 5 when 4 was seemingly released yesterday. Support for the 3 month old 4 has been removed. Corporate administrators uttered a howl of rage. (It can take months to get approval for a new version, so some are steamed up and embarrassed.) I imagine that Mozilla did this deliberately and are happy to lose corporate users. (Chrome goes a different route, updates without asking you. Not sure what corporate take is on that, though maybe the low uptake means it's not really used in that setting anyway.)
2) IE10 preview 2 is now out. The approach here is quite different. (Using the beta's of other browsers is probably similar.) A very interesting feature is that with IE10 they are promising a 10 year support life (like with an OS). This promises some stability (in future) which will appeal to some. Depending on release schedule for IE 11 and beyond it also holds out the possibility of multiple IE versions in our landscape.
I have no time pencilled in to to take IE10 for a test drive, too busy. (It has some nice computational features which appeal.) If anybody else takes it for a spin I'd appreciate feedback on your observations.
