Well..
Of course they could take on more trainees and actually skill someone up in the manner that they require but well thats more costly and time consuming than bitching about the education system isn't it??
I somehow doubt a 21 graduate is going to start knocking up a PS3 title right out of uni and I seriously doubt any uni course could properly educate someone to this level given the usual 2-4 hrs lecturing a week on most courses in a couple of years.
Good of the Industry to point out the failings of the University courses though must really inspire all the kids enrolled on them to continue with their studies...
