You have a good saw. The newer saw simply adds conveniences that your model does not have. Specifically, the blade change mechanism. On the newer model you no longer have to go through a more complicated procedure to change blades. On the new one, blade removal takes about 1 second and putting in a blade takes about 5 or 6 seconds. With the older model you are looking at about 30 seconds for the whole procedudure. IIRC the newer model has a slightly better method of keeping the blade aligned when sawing, and a touch more power. You should be pleased with your new saw providing you use good quality blades. Look at continuing to use Bosch blades. Also don't look at the new one up close if you think you will tire of going through the blade change routine on your current saw.
