Out of the dog's mouth, It's been decided to run upgrades only on A320 as a backbone of flight OPS. Don't think it's got to do with anything else. Simply new people new ideas about how to.... Supposedly 320-330 mixed fleet OPS should be introduced compensating 320 upgrades only, in case, it's been successfully implemented on training level. Sounds like a good idea to me. Time frame is 6-8 months for the scheduled once the rest's gotta figure it out themselves bearing in mind a boost of up to 8 per months has been set as a benchmark. 8 per month sums up to 96 a year that's an industry standard, I'd say, however it's gonna cost about a year to simply spool up the training capacity to reach that level.
All in all sound's theoretically not too bad at all. It remains to be seen, as usual, what the real picture will look like. The new guy faces a tough challenge to restore the credibility of flight OPS. Best of luck and hopefully the plan can be realized in full scope and won't be crisscrossed by politics and other none sense.
DOn't take it personally take it on the rocks!!!
