We managed to find out the exact launching dates for i845E and i845GL chipsets. And as a result, we can now tell when the first Pentium 4 with 533MHz Quad Pumped Bus (i845E is intended for them) and Celeron processors built on the 0.18micron Willamette core (i845GL is developed for them) will come out.

They are said to be coming in May. It is most likely to take place together with the launching of the i845G chipset (mass shipments on May 6, official launch on May 20, see here for more info). However, this is not an exact schedule. This info corresponds pretty well to the already known facts, however, we have to draw your attention to the fact that this chipset launching (and as a result the CPU launching as well) is also delayed, just like in case of i845G (see this news story). As for i845GL, there are no questions here, as it is simply a "lite" version of i845G without the external AGP graphics. Therefore, if one of these chipset is launched, then the launch of another one is inevitable. However, we can’t make out how come that the announcement of i845E is delayed. Suppose that Intel simply sees no need in increasing the Pentium 4 performance before May, as well as in moving its Celeron to a "lite" Willamette core...
