I suggest that comp.sys.intel is a better newsgroup for this query.
But in any case:

There will almost certainly not be a 50MHz 386 from Intel.  Intel
appears poised to try the 286 -> 386sx trick over again, this time
with 386 -> 486.  Keep in mind that the 386 is an old design - it
should be much easier to make a 486 run at 50MHz than a 386.  I'm not
so sure that the marketing trick will work this time, but then there
wasn't any good reason for it to work last time either.

I've seen 33MHz 486s run at 43MHz with fan reliably, and I'm not
certain but that the memory controller quit first.  The implication is
that the .8 micron shrink of the 486 should run at 50MHz fine (whether
anyone can make it pass FCC is another question entirely).
