No. It depends on the status of the development cycle for the next generation of servers and parts/systems stock levels. Some systems are longer-lived in the marketing phase than others. For example, when the 12G systems began sales, you could purchase an R510 or an R520 for only a few short weeks before the R510 disappeared. The R410 and R420 were sold simultaneously for quite a while before the R410 disappeared from Dell's site. Just assume that once a new generation is ANNOUNCED that the life of the model being replaced could end very soon.
