A good way to tell how hard a language is to learn compared with other languages is how long it takes babies to learn to speak it.
I spoke my first sentence at 4 months old, but I don't think that's the average. 
Of course, only now after writing this I remember that we're talking about writing, not speaking. 
I'm not so sure that applies. After all, it takes a child usually around 5-8 years to be able to properly read and speak a language. On average, most languages should take an adult 6-12 months to learn, depending on many factors such as their familiarity with the language's grammatical structure, the language itself, the characters used in the language (ie: for an english speaking person, Italian would be far easier to learn than Japanese (I hear it's one of the easiest secondary languages to learn)).
Anyway, this is getting offtopic, so let's get back to the mod on hand:
How much do you have left to do for an alpha, and when could we see such a release? For an alpha, having icons, balance, etc isn't a huge deal. In fact, even just releasing the models and a rough XML is usually enough for a start (like how Wciow released his Undead mod alpha). It let's us see the units (and stare in awe) even if it isn't properly playable.
