(even though I'm not Hans ...)

No. At least TeX, lua and metapost will probably stay, so that already
adds to three languages :) :) :)

If talking about scripting (ruby, perl) ... in ideal world it should
all end up being lua only (until the next language comes to the
horizon), but there might not be enough motivation to rewrite *all*
the existing scripts, so some of the older scripts (texfont etc.) will
probably stay in ruby/perl for a while/forever unless somebody else
rewrites them or unless Hans will need them.

we'll see how many context+pdftex users are around in a few years from 
now; of course i'll have a few existing workflows that use pdftex (and 
probably for many years) but one seldom needs to generate fonts for that

actually yesterday i had to update a pdftex based style and generate 
tfm's for an ttf font and of course the font was so bugged that i needed 
fontforge to turn it into a proper pfb file with adobe encoding; the 
original had a completely messed glyph names; interesting is that 
mkiv/luatex works ok with that font but of course the unicode vector in 
the pdf will be flaky as well

indeed. most useful script are already converted to lua (mtx-* files 
that run on top of mtxrun); the advantage is that mtxrun has a built in 
filedatabase handler (so we don't use kpsewhich at all) and is pretty fast

the only bit that is still depending on ruby is the index sorting that 
is built in texexec (used by pdftex and xetex) but i could not motivate 
myself to rewrite that bit

the luatx workflow only uses lua and uses luatex itself as lua 
interpreter so there are no dependencies
