In 1.2, the following things will happen:
1) The cost for training will go down across all tiers.
2) The cost for tier 3 speeder models will go up across the board.
3) Certain landspeeder models will be removed from the game (the ones on sale right now).
The net result will be a significant reduction in level-up license training costs as well as a measurable reduction in the acquisition of your level 50 speeder. Purchasing additional speeders at level 50 will be more expensive, something you could call a luxury tax
TL;DR: If you want to game the system and save money, buy your tier 3 speeder now and wait to get the corresponding license after 1.2 goes live.
