sack familiar,
eschew material at 1st level,
bonus 1 heritage feat at 1st level,(draconic, fey, celestial, infernal etc...)
meta magic spells have normal casting time,
diplomacy, intimidate, use magic device and perform class skills,
So... got any reason for Sorcerers to actually stay in the class?

I like Pathfinder's approach of granting bloodline benefits as class features instead of bonus feats: while anybody and their dog can take a feat they like, class features can provide a strong incentive to stay in a class. So those bloodline benefits might be a good start: extra spells known at the levels they're useful at; supernatural abilities that might be useful from time to time; energy resistances/other defensive benefits; specific benefits when casting a certain set of spells etc.
What else can we think of? I'd think long and hard before ditching the familiar. In fact, why not make it a more integral part of what the Sorcerer is "about"? Take it away from the Wizard, fine (maybe give the Wizard some spellbook-related feature instead?). But keep it for the Sorcerer, and make it more interesting, versatile and powerful as you gain levels! Ideas: Familiars that store spell energy; provide a different set of skills than you normally have; can take damage for you; can merge with you for a temporary power boost; can change shape to look like you and fill in as a double; can actually fight well; can learn a spell or two on their own; can transfer wounds/conditions from you to themselves; can provide transportation, crafting, or other utility benefits etc.
All these might be interesting things to incorporate into a familiar at higher levels - not as feats, but as class features, of course.
Other things might be path dependent, allowing one of several options. For example, I can imagine a Sorcerer developing strong metamagic talents over 20 levels (think Incantatrix, but as part and parcel of the base class). Or a Sorcerer developing special summoning/calling talents (take a page from the Malconvoker's and the Thaumaturgist's books). Or a Sorcerer devoted to inspiring others (Bard-, Marshal-, or Dragon Shaman-like class features could be fair game here). Or a Sorcerer going for shapeshifting (Master of Many Forms, Warshaper, and Master Transmogrifist show ways to give good class features for this).
I'm not promoting getting rid of the classes I mentioned, giving all their good stuff to the Sorcerer. But getting some of their good stuff, modify it accordingly (e.g., have it cost spell slots to use those special abilities), and tacking it onto the Sorcerer class might make the Sorcerer appealing to play for more than 5 levels.
