How do you anticipate problems like buggy GL drivers with inconsistent shader implementations? At the rate new devices are coming out it seems impossible for any framework to cover them all.
Fair point, but like I said, if everyone works in bubbles they will all have to deal with this over and over again in different ways. Since these game companies are not actually doing anything for the platform itself, like sharing their libraries for dealing with the issues, they of course will find it painful.
This reminded me completely of the pre-jquery era where if you wanted some advanced JS functionality you'd have to reinvent the wheel over and over in dealing with browser inconsistencies. After years of bitching and moaning people finally released libraries to deal with the issue.
These companies have the right to complain, but complaining will not actually help solve anything except give them a way out avoiding the the complexities of porting platform-specific code to another platform.
